 Posted: Mon Feb 07, 2005 3:52 pm Post subject: nagios configuration question |
 |
|
| I recently set up nagios and I'm trying to get it more functional. I'd like to use the check_by_ssh module to get information on remote hosts such as disk usage(df -h), and cpu utilization(w) and set notifications based on these paramaters. Does anyone have a working example they could share. |

| We have a moderately complex nagios setup, but I haven't been using check_by_ssh. We use the nrpe setup, which works quite nicely. |

| I would prefer not to have to install anything on the client machines. Also security as a big concern in our network so ssh is desirable. |

| In the end I couldn't get the check_by_ssh working properly, so I used nrpe. I would have prefered something with encryption and authentication. |

| We use check_by_ssh for all of our local checks. If you are still looking for help or examples I would be happy to help. |

I would appreciate some examples of a check_by_ssh implementation. I just installed nagios-2.2 but I can't seem to get check_by_ssh working. I've setup pub_keys for authentication, but in the monitor i see this: "Could not create directory '/dev/null/.ssh'."
Any help would be appreciated. Thanks.

First you need to get ssh working between systems for the nagios user. Right now it looks like the nagios user doesn't have a valid home directory, instead just /dev/null. Check the passwd file and set nagios up with a home dir.
Then create nagios users on the remote systems. Verify ssh between nagios users via the IP's rather than the names. Get it all working outside of nagios first. |
