Zabbix template for Zenoss. Unfortunately Zenoss doesn't have powerfull
selfmonitoring. Zabbix solution has been choosed, because realtime log
monitoring. You can find better systems (OpenTSDB, Logstash, ...) for some
particular monitoring problems, but Zabbix is IMHO the best and the most flexible
monitoring system for monitoring of Zenoss in this case. This template is
prepared for Zenoss Core 4.2.5 (all on one node), but it can be modified
for commercial or older versions as well.

These metrics are fetched from Zenoss Daemon Performance metrics (/opt/zenoss/perf/Daemons/*.rrd). I didn't find any way how to obtain them realtime, so RRD files are used. Zabbix doesn't handle NaN value, so NaN is converted to 0.RRDs are not updated realtime, but they can be delayed 5-9 minutes. So rrdtool uses --start and --end time condition:
rrdtool fetch --start=now-15min --end=now-9min <rrd_file.rrd> AVERAGE
Usually only errors or warns are logged in Zabbix. POSIX regular expressions are
used for matching log lines. Exceptions has some "audit" logs e.g. install.log.
All log lines are fetched in this case. Events are raised if you have some new
log lines at the last 10 minutes. Calculated items new log lines at the last
minute, are created, because graph for logs.
Keep in mind, that RabbitMQ metrics need /usr/sbin/rabbitmqadmin, which is not standard part of RabbitMQ. Check http://www.rabbitmq.com/management-cli.html for more informations. You can monitor more RabbitMQ metrics, but only basics (current size of queue and current message queue rate) are enabled.
Every Zenoss is monitored for number of processes, CPU and memory utilization (parsed from ps -u C).
Some known TCP/UDP Zenoss ports are also monitored. If port is TCP, it's also monitored its performance.
Template contains 16 graphs. Selected examples:
Import provided template Zabbix-Template-App-Zenoss.xml and configure Zabbix agent on Zenoss nodes as active agent, because log monitoring. Also include userparameters_zenoss.conf into your zabbix agent configuration (Include directive). Associate Template App Zenoss with your Zenoss hosts. Another recommended standard Zabbix templates for Zenoss: Template OS Linux, Template App MySQL.
