SSH in and run:
./poller.php -h localhost -d -f -m os
Move services in bulk to another host
Services don’t get monitored if a device is down. So if you’re already hosting those services elsewhere it wont get checked until you move them on LibreNMS.
See my community suggestion: Services that are not checked colour
SQL to assign them to another device id:
sudo su mysql
use librenms select * from services where device_id = 44; update services set device_id = 41 where device_id = 44;
You need to monitor HTTPS/HTTP and certificates separately
- For HTTP I suggest:
- For HTTPS I suggest:
-S --sni -t 30
- For certificate I suggest:
-C 27 --sni -t 30
From the man page: man/check_http
-C, --certificate=INTEGER[,INTEGER] Minimum number of days a certificate has to be valid. Port defaults to 443 (when this option is used the URL is not checked.)
Slow or delayed alert notifications
- Check the config using the web UI config validator.
- Check the
php.iniconfig timezone, the configs path maybe something like this:
