Monitor processes /services on Unix systems

I cannot seem to monitor processes/services on unix based systems using SNMP. Everything works well on windows systems.

I have added the services to snmp.conf file as directed on their site, this shows the service, but I cannot seem to detect the state of the service, i.e the service stays permanently up even when the service is shut down to simulate an outage. I guess my problem as to do with the test match pattern value that I need to specify during snmp wizard.

Im using IP Monitor 9.

dont think you can monitor a process directly on a unix server.

one solution is to write a script that checks ps output and returns 0 or 1 state for not running/running, then execute the script when polling SNMP. this would be indirect, but you will get state of a process.

Hi elemzy

Here's how I'm monitoring processes on Ubuntu servers:

- Edit /etc/snmp/snmpd.conf and add a 'proc NAME' entry, where NAME is the name of the process you want to monitor as returned by a 'ps -e' command.

- Restart your snmpd daemon: /etc/init.d/snmpd restart

- In ipMonitor, navigate to your Unix server, add a new Custom SNMP (Wizard) monitor, specify an OID of 1.3.6.1.4.1.2021.2 and click Next. You should get something like this:

The highlighted fifth entry indicates that there is one process running. Click Select on that entry, change the comparison mode to "Pass if Value matches a set of Boolean Rules" and specify Value is == 1.

If you're still having problems matching, try shutting the process down and verify that the fifth entry becomes a zero:

hello simonpt

I see process names instead of just 1s and 0s under value. I selected one process as an example to be monitored. When I click on the select i see the following page. I do not see "Pass if Value matches a set of Boolean Rules" as suggestyed above. What should i choose next?

SNMP Monitor Wizard

SNMPv2-SMI :: enterprises

Name	enterprises
MIB	SNMPv2-SMI
Oid	1.3.6.1.4.1.2021.2.1.2.3
Path	iso . org . dod . internet . private . enterprises . 2021 . 2 . 1 . 2 . 3
Index / Unknown	2021.2.1.2.3

Sample Value

nbsvcmon

Comparison Rules :: String

Please enter the text pattern matching Rules that the SNMP Object should match.


Value will

I see process names instead of just 1s and 0s under value.

Can you please post a screenshot of this?

Ive tried all i could but i cant paste the screenshot.

What i have listed are the services running on the server, instead of numbers.

I select on and i have the page that was pasted above
