Nagios Support Forum

I am using the check_mssql plugin. I didn't write this plugin myself. I configured the service to check MSSQL with the following command: $USER1$/check_mssql -H <host_IP> -U <username> -P <password> This plugin only checks wether it is able to login to the MSSQL engine or not. If it fails to login, ...

I have one other question.
Nagios performs a check every 5 minutes and raises an alert after 5 failed checks. Is it also possible to configure the event handler to occur after 2 or 3 of the checks fail? In that case, Nagios won't perform my failover event handler due to network hickups.

Hi all, I am using the check_mssql plugin for Nagios XI to monitor the MSSQL service on of our servers. Attached to this service is an event handler which performs a failover action in case the MSSQL service goes down. However, Nagios keeps saying every now and then that the MSSQL service is down, w...

I'm not positive, but I am guessing that the user that NSClient++ is running under doesn't have permissions to change the files on other machines.

Thank you Scott. I am facing another problem now. The .bat file, which the NSclient should execute, only does its action on the machine where the .bat is located. For example, in the .bat file are commands described to rename a hosts file in the system32 folder on localhost and also on some hosts in...

Hi Scott, I already got it to work. I misplaced my command under the [External Script] section instead of [External Scripts]. Now it does work when I turn off server A. However, server A is an MSSQL server and I actually want Nagios to perform the action as soon as the MSSQL Server Agent stops worki...

When I run the command i get the following:
UNKNOWN: No handler for that command

Hope you can help me out.

Thanks again for your response. I still can't get the command to work. I did everything Scottwilkerson described. Then I turned on the option "Event handler enabled"=on on server A in Nagios. After that, I stopped and started the nsclient on the destination machine (server B). But still, w...

Hello, I have 10 IIS Windows servers on which the action should be performed. Could you tell me if the following is possible? On the New Command page, configure the following command: $USER1$/check_nrpe -H <SERVER_B_IP> <SERVER_C_IP> <SERVER_D_IP> <SERVER_E_IP> ... -c a_is_down Thanks in advance.
