monitis agent over proxy (McAfee Web Gateway 7.6.1.2.0.21212)

Jump to solution

since years we use monitis agent on linux.

shortly we got a proxy-server to route outgoing traffic from our servers to monitis-servers (agent1.monitoringnet.com agent2.monitoringnet.com).

what we have now (monitis-agent on linux 64bit, agent version 4.02.65).

  • tomcat monitor is working fine over McAfee Web Gateway 7.6.1.2.0.21212, we get data in our dashboard on monitis.
  • process/server-monitors (cpu and process-java) have troubles (ERROR: ssu_receive_response: select: Connection timed out. | Unable to establish connection to the server.).

monits-support cannot tell, whats wrong (i.e. the say this is your proxy) but neither can explain why one monitor (tomcat) works fine while the others do not...

? has anyone experience with a similar setup  too?

at the moment we do not have access to ops-people (log of proxy, configuration)

Hello,

I quickly registered at Monitos and tested it in my lab. I was able to see the same kind of error messages, although it seemed most things were working fine. I think this is related to SSL inspection. I added agent1.monitoringnet.com and agent2.monitoringnet.com into the "Tunneled Hosts" list to avoid MWG decrypting the traffic. By doing to the error messages disappeared.

Best,

Andre

thanks andre for your quick response and your effort testing this on your part. tomorrow i have a meeting with ops-person of web gw and i ask him to do same as you: add the two monitis-hosts to the "tunneled hosts" list (guess the person is able to find this somewhere in the configuration jungle... )

andre: could contact ops-guy. he added the hosts and voila - it works

up to this the data within the red frame (cpu-monitor, java-process monitor) on screen-shot was empty ("nothing to display")  - now it is OK

thanks a lot!
