This SSH-based ZenPack provides TCP state statistic for IPv4 and IPv6.

You must first have, or install, Zenoss 4. This ZenPack was tested against Zenoss 4.2.5. You can download the free Core version of Zenoss from http://community.zenoss.org/community/download.
On monitored system, /bin/cat command must be installed and SSH daemon properly configured. ZenPack fetchs statistic from /proc/net/tcp and /proc/net/tcp6, so /proc filesystem must be mounted. Notes:
- netstat command is slow (especially if you have box with 40k connections)
- ss command is quick, but its location depends on Linux distribution
- the best approach is using directly /proc/net/tcp(6) in this case
Download the egg file http://wiki.zenoss.org/download/zenpacks/ZenPacks.JanGaraj.TcpStat/1.0.0/ZenPacks.JanGaraj.TcpStat-1.0.0.egg . Copy this file to your Zenoss server and run the following commands as the zenoss user.
zenpack --install ZenPacks.JanGaraj.TcpStat-1.0.0.egg
zenoss restart
If you wish to further develop and possibly contribute back to the TcpStat ZenPack you should clone the git repository https://github.com/monitoringartist/ZenPacks.JanGaraj.TcpStat, then install the ZenPack in developer mode using the following commands.
git clone git://github.com/monitoringartist/ZenPacks.JanGaraj.TcpStat.git
zenpack --link --install ZenPacks.JanGaraj.TcpStat
zenoss restart
Please configure device SSH settings properly (zCommandUsername, zCommandPassword/zKeyPath)
Go to the specific device (yes, it needs to already be added) and bind TcpStat/TcpStat6 templates.
Installing the ZenPack will add the following items to your Zenoss system:
- /Devices/Server/rrdTemplates/TcpStat
- /Devices/Server/rrdTemplates/TcpStat6
- /Events/Status/TcpStat
