Understand the alert

This alert is related to your American Power Conversion (APC) uninterruptible power supply (UPS) device. The Netdata Agent monitors the number of seconds since the last successful data collection by querying the apcaccess tool. If you receive this alert, it means that no data collection has taken place for some time, which might indicate a problem with the APC UPS device or connection.

Troubleshoot the alert

1. Verify the apcaccess tool is installed and functioning properly

   $ apcaccess status
   

   This command should provide you with a status display of the UPS. If the command is not found, you may need to install the apcaccess tool.

2. Check the APC UPS daemon

a. Check the status of the APC UPS daemon

   $ systemctl status apcupsd

b. Check for obvious and common errors, such as wrong device path, incorrect permissions, or configuration issues in /etc/apcupsd/apcupsd.conf.

c. If needed, restart the APC UPS daemon

   $ systemctl restart apcupsd

1. Inspect system logs

Check the system logs for any error messages related to APC UPS or apcupsd, which might give more insights into the issue.

1. Verify UPS Connection

Ensure that the UPS device is properly connected to your server, both physically (USB/Serial) and in the configuration file (/etc/apcupsd/apcupsd.conf).

1. Update Netdata configuration

If the issue is still not resolved, you can try updating the Netdata configuration file for the apcupsd_last_collected_secs collector.

1. Check your UPS device

If all previous steps have been completed and the issue persists, your UPS device might be faulty. Consider contacting the manufacturer for support or replace the device with a known-good unit.
