why sometimes the monitoring engine status display "no data"?!

Hello @xpertech,

Looks like the dashlet is updating but it's not able to fetch any data. Have you made any changes to the server since this started happening? The data is retrieved from a php script running on a scheduled basis as a cron job.

1. Please post the output of the cron log

Code: Select all

tail -n 25 /var/log/cron

2. Load the this page and tail the Apache log and post the output. Thanks.

Code: Select all

tail -f /var/log/httpd/*error_log /var/log/httpd/*access_log

Hello @Xpertech

The logs contain the error below on the script that is parsing the status data for the server. This is a known issue that will be patched in the next maintenance release.

PHP Warning: simplexml_load_string(): in /usr/local/nagiosxi/html/includes/utils-systat.inc.php on line 17

If you'd like to fix this right away, see the forum post below. Also, be sure to make a backup copy of manage_services.sh before making any changes.
