Add convert processor #11686

andrewkroh · 2019-04-07T23:30:40Z

The convert processor converts a field in the event to a different type, such
as converting a string to an integer. For a full description of the processor's
capabilities see the add documentation.

Closes #8124

jenkins, test this

The part I don't like too much about the convert processor is that it does not only convert but also rename and copy. I understand that it makes it for the user much easier to configure. What bugs me is that so far each processor had mostly only 1 tasks and because of that pretty simple. To achieve a bigger goal, they had to be combined.

I was first thinking if the rename processor could be called from the convert processor to reuse some code but I think it makes the code actually more complicated.

libbeat/processors/convert/convert.go

+			t, err := p.transformType(conv.Type, v)
+			if err != nil {
+				if !p.IgnoreFailure {
+					return event, annotateError(p.Tag, errors.Wrapf(err, "unable to convert field [%v] value [%v] to [%v]", conv.From, v, conv.Type))


Right now on failure the event might be already modified by previous fields. Is this expected or should it reset to the original event? I think we do that in other processors. Same above with ignore missing.

@ruflin I have finally addressed this and added a few tests to check that the event is not modified at all if there is a failure.

is that it does not only convert but also rename and copy.

The ingest node convert processor does a copy. Adding the ability to choose rename over copy is something I added. The reason I want the option to rename is to tie it in with the conversion such that the source field can be deleted iff the conversion is successful. This makes it possible to degrade gracefully if some of the data you are transforming isn't perfect.

For example if I'm trying to move event_data.SourceIP to source.ip but the value is - then the conversion will fail because the IP in invalid (which is great because it will prevent an ES mapping type exception later). In that failure case I want to retain the original field event_data.SourceIP. And if it's a valid IP then want to drop the event_data.SourceIP field.

Without the rename option you could accomplish this with a convert followed by conditional drop_fields for each field (that would be kind of tedious). You should not use a rename processor followed by convert because that could get you into a mapping exception if you end up writing say a string into a field that's mapped as ip.

I guessed that you got inspirted by the other convert processors. I'm good with moving forward as you suggested.

Couple of comments about config flags

adriansr · 2019-05-02T13:39:29Z

libbeat/processors/convert/config.go

+	Fields        []field `config:"fields" validate:"required"` // List of fields to convert.
+	Tag           string  `config:"tag"`                        // Processor ID for debug and metrics.
+	IgnoreMissing bool    `config:"ignore_missing"`             // Skip field when From field is missing.
+	IgnoreFailure bool    `config:"ignore_failure"`             // Ignore conversion errors.


Beats processors have been using a fail_on_error flag defaulting true for this. I do like more ingest processor's ignore_failure, was this on purpose?

Good point. I changed it to fail_on_error. I was modeling it directly off of the Ingest Node processor and neglected to notice this convention in Beats.

Here, @urso suggests adding a case for arrays too.

I added a simple case for []interface{}

Thanks, I copied that in.

* Use time.Duration directly in GetStartTimeEndTime function (#12033) * Remove convertPeriodToDuration and use duration directly in GetStartTimeEndTime * Pass period in time.Duration type * Fix memory leak in Filebeat pipeline acker (#12063) * Fix memory leak in Filebeat pipeline acker Before this change acker goroutine was kept forever as processed events count was not correctly updated. Filebeat sends an empty event to update file states, this event is not published, but treated as dropped, without updating counters. This change makes sures that `a.events` count gets updated for dropped events also, so the acker gets closed after all ACKs happen. * Add convert processor (#11686) The `convert` processor converts a field in the event to a different type, such as converting a string to an integer. For a full description of the processor's capabilities see the included documentation. Closes #8124 * Update docs.asciidoc (#11852) (#12045) * Update docs.asciidoc Added in a short note on a few of the other configurable variables. * Make update * Remove systemd v233 requirement because it's no longer true (#12076) * Don't generate autodiscover config when no port matches host hints (#12086) On metricbeat, when the host autodiscover hint is used, and it includes the port, one of the exposed ports has to match with the one in the hint. If not, no configuration should be generated. If it is generated, it will have empty hosts, what would lead to unexpected errors as the seen in #8264. * Fix transptest testing (#12091) Rewrite test for more clarity ensuring that the server and listeners are stopped before the test function returns (cause for the case condition). Each test has it's very own socks5 server now. Tests not requiring a proxy don't spin up one. * Refactor and add tests for template and ilm handling. (#12065) Refactor and add more tests related to setting up template and ilm policy. Ensure template and ilm-policy is exported despite enabled=false setting. * [Auditbeat] Login: Fix re-read of utmp files (#12028) The `login` dataset is not using the previous file offset when reading new entries in a utmp file. As a result, whenever a new login event occurs, all records are re-read. Also expands the documentation, moves test files to testdata/, and adds a test case that adds a utmp record to the test file and re-reads it to make sure this bug does not happen again. * [Metricbeat][postgresql] Update lib/pq to fix #11393 (#12094) This updates github.com/lib/pq to the latest version to fix a socket leak when SSL is not enabled on the PostgreSQL server. Fixes #11393 * Make breaking changes separate files (#12002) * Change image references to use block syntax not inline (#11911) * Change image references to use block syntax not inline * Fix format for inline links * Revert "Make breaking changes separate files (#12002)" (#12116) This reverts commit c17586a. * fix queue.spool.write.flush.events config type (#12080) * Revert printing template and policy name on export. (#12067) Ensures behavior on running the `export` cmd does not change compared to last released version. * [Filebeat] Add -expected files by default (#12041) So far expected files in Filebeat tests were only generated and compared when a file exists. This changes to create a generated for all example logs. This will add a few more files to the repository but I think there the benefits outweight the costs as it means the modules are tested in more detail. Also minor changes will be detected easier. * Update vendored gosigar to 0.10.2 (#12101) #11924 duplicated some code from go-sysinfo that is affected by a memory leak (fixed in #12100) In this case, only master is affected as the PR that introduced the leaky gosigar wasn't backported. * Fix various memory leaks under Windows (#12100) A function in go-sysinfo used under Windows to split a command-line into arguments was leaking memory. This code was used in various places: add_process_metadata processor. (enabled by default in all Beats) Packetbeat's process monitor. (disabled by default). Auditbeat's system/process metricset. This PR updates vendored go-sysinfo to the most recent version, which fixes the leak. * New processor extract_array (#11761) This adds a new processor, extract_array, that allows accessing values inside arrays and copying them to target fields. * [Heartbeat] Remove not needed flags from setup command (#11856) The setup command until now contained all the possible options from the other Beats. As Heartbeat does not ship anymore with dashboards, the --dashboards command is not needed anymore and is only confusing. I also removed all the other commands except `--ilm-policy` and `--template`. I'm not aware that `--pipelines` or `--machine-learning` would be used. Here the comparison between `./heartbeat setup -h` from before and after. Before: ``` This command does initial setup of the environment: * Index mapping template in Elasticsearch to ensure fields are mapped. * Kibana dashboards (where available). * ML jobs (where available). * Ingest pipelines (where available). * ILM policy (for Elasticsearch 6.5 and newer). Usage: heartbeat setup [flags] Flags: --dashboards Setup dashboards -h, --help help for setup --ilm-policy Setup ILM policy --machine-learning Setup machine learning job configurations --pipelines Setup Ingest pipelines --template Setup index template ``` After: ``` This command does initial setup of the environment: * Index mapping template in Elasticsearch to ensure fields are mapped. * ILM Policy Usage: heartbeat setup [flags] Flags: -h, --help help for setup --ilm-policy Setup ILM policy --template Setup index template ``` In this PR I did not include a check for the config option `setup.dashboards` to make sure they are not there like apm-server does (https://github.com/elastic/apm-server/blob/2baefab778fdfe70c47bc2fb488677b2e43e4635/beater/beater.go#L60) as I don't think it's necessary. * Skip Windows testing if magefile.go does not exist (#12099) Changes the jenkins_ci.ps1 script to skip testing when magefile.go does not exist. This will allow us to add projects like x-pack/winlogbeat to the test matrix because not all branches have an x-pack/winlogbeat/magefile.go file. * Fix goroutine leak on initialization failures of log input (#12125) Outlets are created during log input initialization, and if it fails they were never freed. Handle this case. * Document and improve permission checks when running socket metricset from Docker (#12039) Update instructions for system/socket metricset on Docker. And base permission checks on capabilities rather than on the effective uid. Running a process as root doesn't mean that it has all privileges, specially when run as container. * [metricbeat] added CPU usage check to docker memory stats (#12062) * Change type from scaled_float to long and add format (#11982) * Change type from scaled_float to long and add format * [libbeat] Add unit tests for libbeat's client proxy settings (#12044) These tests set up server listeners and create libbeat clients with varying proxy settings, and verify that the clients ping the correct target URL. This is a preparation for #11713, since most of the logic (and work) is in testing the proxy settings; the much simpler PR adding the proxy-disable flag will be a followup to this one, to keep the functional changes isolated in case of rollbacks etc. * [Metricbeat](Etcd-Leader)Followers wont report leader metrics (#12004) * manage leader metricset so that followers don't report errors nor events * add debug message when skipping leader events from non leader members * Add package libbeat/common/cleanup (#12134) * Add package libbeat/common/cleanup The cleanup package adds helpers for deferred optional cleanup on errors. For example: ``` ok := False defer cleanup.IfNot(&ok, func() { ... }) // continue initialization ok = True return // some value ``` * Add changelog entry * [docs] add make fmt to contributing guide (#12118) * Move one changelog entry from breaking change to bug fix (#12146) * Sysmon and Security "modules" for Winlogbeat (#11651) Add pipelines for the Security and Sysmon event logs The Security processor handles just three events to start with - 4624, 4625, and 4648. These are event.category=authentication events. The Sysmon processor handles all event IDs found in the sysmon manifest (sysmon -s). It moves the event_data fields that are in ECS and does some type conversions. * [Auditbeat] Process: Add hash of executable (#11722) Adds the hash(es) of the process executable to `process.hash.*`. The default is to add SHA-1 only as `process.hash.sha1`. * [Docs] Comment out section that contains bad link (#12152) * [Filebeat] Introduce UTC as default timezone for modules tests (#12120) Currently all our modules have convert_timezone disable by default. The reason in 6.x for this was probably that 6.0 did not support convert_timezone and we did not want to introduce a breaking changes. New modules should have convert_timezone enabled by default. If a module has convert_timezone enabled by default the tests will fail as it takes the timezone of the local computer. To circumvent this, this PR sets the timezone of the tests to UTC so the same time zone is always used. No generated files were changed in this PR as all modules have convert_timezone off by default. But it will affect #12079 and #12032 * Add number of goroutines to reported metrics (#12135) * Add minimal ES template functionality. (#12103) When loading a template without fields, create a minimal template only applying given configuration, without any default values for mappings and settings. This allows to create additional templates only defining specific values. * Refactor logging in pgsql module (#12151) Guard debug logging statements with "isDebug" checks. And switch the module over to using named loggers. Fixes #12150 * Ignore doc type in ES search API for ES 8 (#12171) * [Docs] Make breaking changes separate files for each version (#12173) * [Filebeat] module for palo_alto (pan-os) logs (#11999) This is a module for Palo Alto Networks PAN-OS logs received via Syslog. It has been tested with logs for PAN-OS version 7.1 to 9.0. However, it is expected to work with earlier versions as the log format is compatible. * [cmd setup] Add and deprecate setup cmds for index handling (#12132) Deprecate `setup --template` and `setup --ilm` in favour of newly introduced `setup --index-management` command. Fix bug in template and write alias creation order to ensure creating properly managed indices. implements #12095 Co-authored-by: steffen.siering@elastic.co * Zdd zfs beat (#12136) Querying ZFS Storage and Pool Status * [metricbeat] Expand metricbeat dev guide for testing (#12105) * update dev guide to add examples and expand testing * Bugfix set template.order to 1 by default. (#12160) To ensure default order is not changed to 0, set it to 1 in default config. * [Auditbeat] Fix issues with multiple calls to rpmReadConfigFiles (#12168) This patch fixes two issues in Auditbeat's system/package on RPM distros: - Multiple calls to rpmReadConfigFiles lead to a crash (segmentation fault). It is necessary to call rpmFreeRpmrc after each call to rpmReadConfigFiles. See [1] for a similar issue. - In addition, it is also necessary to call rpmFreeMacros (when available) to avoid leaking memory after each rpmReadConfigFiles call. 1: https://lists.fedorahosted.org/pipermail/anaconda-patches/2015-February/015826.html Fixes #12147 * [Filebeat] Palo_alto module improvements (#12182) This PR adds some missing features to the recently merged palo_alto module: Dashboards (One for traffic logs, one for threats). Sets network.type to either ipv4 or ipv6. Renames palo_alto.pan_os.threat_file_or_url to palo_alto.pan_os.threat.resource.

This new `container` input offers the same wrapper to read log files from containers with the following changes: * It exposes `paths` as the `log` input, instead of `containers.ids` and `containers.path`. * `parse_flags` and `combine_partials` are hardcoded, as there is no good reason to disable them. * `stream` selector is still available, under root settings. * It allows to select the log format (also atodetect it), giving room for future format changes. `format` can be `auto` (default), `docker` and `CRI`. Example configurations: Get Docker logs: ``` filebeat.inputs: - type: container paths: - /var/lib/docker/containers/*/*.log ``` Get Kubernetes logs: ``` filebeat.inputs: - type: container paths: - /var/log/pods/*/*/*.log # this could also be used: #- /var/log/containers/*.log ``` Previous `docker` input is deprecated in favor of this, to be removed in 8.0 * [Auditbeat] Fix formatting of config files on macOS and Windows (#12148) Fixes formatting of auditbeat.yml and auditbeat.reference.yml across platforms. * [libbeat] Escape BOM on JsonReader before trying to decode line (#11661) * fix json bom + testing * Set beat ID in registries after loading meta file (#12180) * Reset beat ID in registries in case loaded from meta file * Set, not reset * Adding CHANGELOG entry * [Filebeat] Move dashboards from 8 to 7 directory (#12217) The CoreDNS and Envoyproxy dashboard were in the 8 instead of 7 directory.
