Hi Support,

We noticed that the nagiosxi after sometime was giving the status pending as seen on the screenshot.

Please advise on how to resolve such issue.

OS: RHEL 7.2
NagiosXI Version: 5.2.9

Thank you very much.

Please run the following commands:

Code: Select all

service nagios stop
service mysqld start
mysqlcheck -s -u"root" -p"XXXXXXX" --all-databases 2>&1
rm -f /usr/local/nagios/var/retention.dat
service nigios start

Let me know if this resolves your issue.

Hi Support,

We did the nagios service restart however, the issue keeps recurring after a period.

Will there be any impact of the nagios if the following is executed rm -f /usr/local/nagios/var/retention.dat,

[bolson]

Deleting retention.dat won't cause any issues as it will be recreated. The purpose of the file is to save service state information across reboots or restarts of the nagios service. You could simple rename the file rather than removing it:

Code: Select all

mv /usr/local/nagios/var/retention.dat /usr/local/nagios/var/retention.dat.bak

Let's also verify there is only one parent nagios process

Code: Select all

ps -ef|grep bin/nagios
