Samba AD Checks

Simple script sensors for PRTG by Paessler to check the health of a Samba AD

The first script - ad_check_db.sh - is using samba-tool dbcheck to get just the checked objects and found errors.

The second script - ad_check_rep - is using samba-tool drs showrepl to look for errors in replication. This script uses the JSON output to show the last time of replication and its status. It's similar to the original PRTG sensor except it shows the data for each naming context in one senor. If you're using a samba-tool version which doesn't support json output the old version is still located in the "Old" folder.

Both sensor have set a standard warning limit of zero so when at least one error is counted the sensor goes into warning state.

Prerequisites

Be sure you have set correct logon values for SSH in your device.

I personally use "Login via private key" with an user especially for monitoring which also may use sudo for this script without a password.

Installing

Place the script to /var/prtg/scriptsxml on your Synology NAS and make it executable. (You may have to create this directory structure because PRTG expects the script here.)

For ad_check_db.sh:

wget https://raw.githubusercontent.com/WAdama/Samba_AD_Checks/master/ad_check_db.sh
chmod +x ad_check_db.sh

For ad_check_rep.sh:

wget https://raw.githubusercontent.com/WAdama/Samba_AD_Checks/master/ad_check_rep.sh
chmod +x ad_check_db.sh

On your PRTG system place the file prtg.standardlookups.nas.adstatus.ovl in INSTALLDIR\PRTG Network Monitor\lookups\custom and refresh it under System Administration / Administrative Tools

In PRTG create under your device which represents your Samba AD DC a SSH custom advanced senor.

Choose under "Script" the script you want to use and enter for the mail versions under "Parameters" the e-mail address which should get the mails.
