For Netlsnr agent, the detail monitoring is not enabled by default to monitor the listener process.

You can enable detail monitoring for Netlsnr by specifying a value for the MonScript attribute. The example to set up detail monitoring uses the supplied monitor script for Netlsnr, /opt/VRTSagents/ha/bin/Netlsnr/LsnrTest.pl. The detail monitoring script for the Netlsnr resource uses the Listener command lsnrctl status $Listener to test the Listener process.

To disable detail monitoring for Netlsnr

Disable detail monitoring by setting the MonScript attribute to an empty string:

# haconf -makerw
# hagrp -freeze service_group
# hares -modify LsnrResource MonScript ""

# hares -override LsnrResource LevelTwoMonitorFreq
# hares -modify LsnrResource LevelTwoMonitorFreq 0

# haconf -dump -makero
# hagrp -unfreeze

To set up detail monitoring for Netlsnr

Make the VCS configuration writable:
```
# haconf -makerw
```
Freeze the service group to avoid automated actions by VCS caused by an incomplete reconfiguration:
```
# hagrp -freeze service_group
```

Enable detail monitoring by entering the following commands:

# hares -modify LsnrResource MonScript "./bin/Netlsnr/LsnrTest.pl"

# hares -override LsnrResource LevelTwoMonitorFreq
# hares -modify LsnrResource LevelTwoMonitorFreq 1

# haconf -dump -makero

# hagrp -unfreeze service_group
