I have just discovered Librenms and am in the process of setting it up. Hope someone may be able to help with some questions please.
This is set up on Docker with the latest image.
I have 289 devices in the database
Everything is running fine for around 24 hours but then I get the error message that polling has not completed in the past 5 minutes. It is like the polling service just stops! If I restart Librenms it runs again for around 24 hours and dies again.
I have been running tail -f /data/logs/librenms.log and see the polling taking place against each device but when it dies I see no more polling entries in this files
I have added the below to my config.php
$config[‘service_poller_workers’] = 48; # Processes spawned for polling
$config[‘service_services_workers’] = 16; # Processes spawned for service polling
$config[‘service_discovery_workers’] = 16; # Processes spawned for discovery
$config[‘service_poller_frequency’] = 300; # Seconds between polling attempts
$config[‘service_services_frequency’] = 300; # Seconds between service polling attempts
$config[‘service_discovery_frequency’] = 21600; # Seconds between discovery runs
$config[‘service_billing_frequency’] = 300; # Seconds between billing calculations
$config[‘service_billing_calculate_frequency’] = 60; # Billing interval
$config[‘service_poller_down_retry’] = 60; # Seconds between failed polling attempts
$config[‘service_loglevel’] = ‘INFO’; # Must be one of ‘DEBUG’, ‘INFO’, ‘WARNING’, ‘ERROR’, ‘CRITICAL’
$config[‘service_update_frequency’] = 86400; # Seconds between LibreNMS update checks
Watchdog service. Restarts poller if it dies.
$config[‘service_watchdog_enabled’] = true;
From Poller Cluster Health (when it is working) I see:
Poller Workers 48
Devices Actioned 297
Worker Seconds 3436/14400
From Poller Cluster Health (when it dies) I see:
Poller Workers 48
Devices Actioned 0
Worker Seconds 0/14400
Am I correct in thinking that Librenms no longer uses CRON? I have no CRON image loaded via my docker-compose.yml ?
Could someone please suggest how to go about trouble shooting this, I am struggling at the moment.
I have added the validate file below. I see the couple of errors in the output and am also trying to fix those I have checked my PATH based on a couple of suggestions in other doc’s but doesn’t seem to sort it.
/opt/librenms # ./validate.php
Do not run validate.php as root
/opt/librenms # su librenms
