Resolution

After changing the IP address of the ADM aggregator, you must update the configuration files of all probes on each collector to point to the new IP address.

Configuring the listener (used for Passive Discovery)

1. Log in to the collector(s) as root.
2. Open the /home/nlayers/Seneca/probe/probe-params.custom.txt file.
3. Set the -e parameter to the new IP address of the aggregator:
   
   -e <Aggregator IP>
   
   
4. Save the file.
5. Run this command to restart the probe:
   
   adm_control.pl --restart listener

Configuring the Linux Active Probe (used for Detail and IP Discovery)

1. Log in to the collector(s) as root.
2. Open the /home/nlayers/Seneca/ActiveProbe/conf/ap.remote.comm.custom.properties file.
3. Set the ap.server.ip parameter to the new IP address of the aggregator:
   
   ap.server.ip=<Aggregator IP>
   
   
4. Save the file.
5. Run this command to restart the probe:
   
   adm_control.pl --restart active_probe

Configuring the Windows Active Probe (used for WMI Detail Discovery)

1. Log in to the Windows machine running the ADM WMI Probe service using RDP or VNC.
2. Open the <Install directory>\conf\ap.remote.comm.custom.properties file.
3. Set the ap.server.ip parameter to the new IP address of the aggregator:
   
   ap.server.ip=<Aggregator IP>
   
   
4. Save the file.
5. Restart the probe using the services control panel or command line.
