monitoring-scripts

These are just some scripts I use to monitor my servers. I usually put them all in /usr/local/sbin.

• monitorvars.conf - main configuration file. Set an IP address to exclude, as well as the EMAIL address to send notifications to.
• monitordisk.sh - monitors disk usage. Creates a file in /tmp and sends its content to the EMAIL defined above.
• monitorload.sh - monitors server load. Creates a file in /tmp and sends its content to the EMAIL defined above.

The scripts above should be have crontab entries for them. I usually set something like:

#Ansible: monitordisk.sh
0 7,15,23 * * * /usr/local/sbin/monitordisk.sh
#Ansible: monitorload.sh
*/10 * * * * /usr/local/sbin/monitorload.sh

• ssh-alert.sh - script to send an email notification whenever someone successfully signs in using ssh. Must be called via pam. Add in /etc/pam.d/sshd the following line:

  session optional pam_exec.so seteuid /usr/local/sbin/ssh-alert.sh
