nagios password expiration - no processing of perf data

[jhalbert]

In our installation of Nagios XI, performance data has stopped processing because it appears that the nagios account password has expired. Trouble is, the web interface under account management only shows a nagiosadmin account and not a nagios account. How can I reset the password to the nagios account?

[jhalbert]

I have found that using the chage command as shown below re-enables a password that has expired and resolves the performance data processing issue:

chage -M 99999 nagios

I do have further questions, when does the nagios account get created? How do you determine what the password for the nagios account is? Further, if I change the password with the passwd command, will it break anything? Hopefully, a default password is not embedded in any code.

Thanks for answering this.

This is covered in https://support.nagios.com/kb/article/n ... ems-9.html where it is recommended to run the following to re-enable the account:

chage -I -1 -m 0 -M 99999 -E -1 nagios

The account is created during the install with the command:

useradd nagios

There shouldn't be a password set. You can make there isn't by checking/changing /etc/shadow: where you'll find a line like:

nagios:!!0:99999:7:::

Note the !! . If a password was set you would see this replaced with a long random string.
