Monitoring

If you have a Zero Service running at some URL like http://zero.example.org/zero/, it’s quite simple to connect host objects in Nagios to the correct view of performance data.

Nagios provides two host attributes for this purpose: action_url, notes_url

SNMP (at least NET-SNMP in Linux) is providing enough data to setup checks for CPU, memory, disk and processes to a standard Nagios.

We updated the Zero packages on SourceForge.net yesterday.

It’s done, yesterday we published an important update of the Zero RRD Framework at SourceForge. You will find the latest code in the SubVersion Repository, but also a snapshot in the Download Section.

You can just download and extract the tar.gz archives for zerod and zero-agent in your /opt folder and follow the manual in the doc folder.

Any feedback and help is appreciated.

To fix the recent failure of Network UPS Tools on my APC Back-UPS attached to Debian Etch, I used a pragmatic approach:

• The problem with a missing or changing USB device is fixed by udev providing a static device name.
• The 2nd problem with a crashing newhidups driver is solved by monit.

Soon SourceForge.net will present a new release of the Zero RRD Framework, that provides a simple but powerful service for real time graphs.
