+We have moved away from Zenoss, it was getting too old and throwing false alerts. It relies on SNMP and we wnated to go agent based. For the speed of installion we first installed Ganglia (not developed anymore but an awesome package based tool). Then we added Zabbix for completion.  Details at [[cluster:227|HPC Monitoring]]

 ==== Zenoss ====
-Our scratch server has been our Zenoss server since the beginning. Ran RHEL 5.5 and is now decommissioned. A new server has deployed to only do the Zenoss service.  It will run CentOS 6.10 (Final) and Zenoss 4.2.5, specifically the Community last v4 version becasue I like to keep it simple. All we want is basic monitoring, alerts when nodes go down, and historical data.

+# never understood why
+rpm -e --nodeps mysql mysql-server mysql-libs mysql-devel postfix
+# autodeploy
+mkdir zenoss-deploy
+cd zenoss-deploy/
+wget https://github.com/zenoss/core-autodeploy/tarball/4.2.5 -O auto.tar.gz
+tar zxvf auto.tar.gz

+At this point the script fails to find the core rpm file for my distro. Luckily, there are some folks maintaining the script for 4.2.5 and pointing to the new location. Shout out to Jane, much appreciated!
+Download the zip file from github.com [[https://github.com/jcurry/Zenoss_4.2.5_core-autodeploy|Zenoss_4.2.5_core-autodeploy]]
+<code>
+# Stage the maintained autodeploy script
+cp /root/Zenoss_4.2.5_core-autodeploy-master.zip .
+unzip Zenoss_4.2.5_core-autodeploy-master.zip

+./core-autodeploy.sh_update_20190110_zenup

+Then test out the installation.
