 ## APEL Plugin
 
-TODO
+The APEL plugin creates job summary records and sends them to APEL.
+The following fields need to be present in the config file:
+
+```
+[logging]
+log_level =
+
+[paths]
+time_db_path =
+
+[intervals]
+report_interval =
+
+[site]
+publish_since =
+sites_to_report =
+site_name_mapping =
+default_submit_host =
+infrastructure_type =
+benchmark_type =
+
+[auditor]
+auditor_ip =
+auditor_port =
+auditor_timeout =
+benchmark_name =
+cores_name =
+cpu_time_name =
+nnodes_name =
+meta_key_site =
+meta_key_submithost =
+meta_key_voms =
+meta_key_username =
+
+[authentication]
+auth_url =
+ams_url =
+client_cert =
+client_key =
+ca_path =
+verify_ca =
+```
+
+`log_level`: can be set to `DEBUG`, `INFO`, `WARNING`, `ERROR`, or `CRITICAL` (with decreasing verbosity).
+`time_db_path`: path of the `time.db`. The database should be located at a persistent path and stores the end time of the latest reported job, and the time of the latest report to APEL.
+`report_interval`: time in seconds between reports to APEL.
+`publish_since`: date and time (UTC) after which jobs will be published. Only relevant for first run when no `time.db` is present yet.
+`sites_to_report`: list of sites that will be reported. Uses the site name as stored in the AUDITOR records.
+`site_name_mapping`: maps the site name as stored in the AUDITOR record to the name of the site in the GOCDB.
+`default_submit_host`: default submit host if this information is missing in the AUDITOR record.
+`infrastructure_type`: origin of the job, can be set to `grid` or `local`.
+`benchmark_type`: name of the benchmark that will be reported to APEL.
+`auditor_ip`: IP of the AUDITOR instance.
+`auditor_port`: port of the AUDITOR instance.
+`auditor_timeout`: time in seconds after which the connection to the AUDITOR instance times out.
+`benchmark_name`: name of the `benchmark` field in the AUDITOR records.
+`cores_name`: name of the `cores` field in the AUDITOR records.
+`cpu_time_name`: name of the field that stores the total CPU time in the AUDITOR records.
+`nnodes_name`: name of the field that stores the number of nodes in the AUDITOR records.
+`meta_key_site`: name of the field that stores the name of the site in the AUDITOR records.
+`meta_key_submithost`: name of the field that stores the submithost in the AUDITOR records.
+`meta_key_voms`: name of the field that stores the VOMS information in the AUDITOR records.
+`meta_key_user`: name of the field that stores the GlobalUserName in the AUDITOR records.
+`auth_url`: URL from which the APEL authentication token is received.
+`ams_url`: URL to which the reports are sent.
+`client_cert`: path of the host certificate.
+`client_key`: path of the host key.
+`ca_path`: path of the local certificate folder.
+`verify_ca`: controls the verification of the certificate of the APEL server. Can be set to `True` or `False` (the latter might be necessary for local test setups).
+
