I recently tried the OpenSTA (open source tool originally created by Cyrano, source code release under GNU licence) test tool and it seems like it could be very useful.
I would like to use it at first to monitor performace on Solaris machines in my test environment (simple stats like CPU and Mem usage would be fine). I can not find ANY info on how to do this... The OpenSTA documentation gives about 1 line to this topic "create an snmp collector and query results from SNMP agents"...
After scouring the net, all I can find is info on SNMP agents for routers and networking gear. Does such a think exist for the Solaris O/S?
Is what I want to do possible? OpenSTA makes it sound like it very simple and then gives you absolutely no information on how to do it.
Im not sure that OpenSTA had an SNMP monitor for those things. Firstly can you see the solaris machine from the PC your on? E.g. can you ping that machine? If you can then you set up the monitor by selecting the PC name (network name of the solaris box) and when setting up the monitor you will be shown what SNMP monitors are available. But it would be good to do another search on the internet for a general guide of SNMP so you can see what each monitor does.
thanks for the tip.. I got a little further on this problem yesterday. With OpenSTA I can do an snmp server scan and I am finding some sort of SNMP agent on the solaris box. However, the queries for the snmp agent i see don't really give me the stats I want (they deal with I/O and network stats, I am looking for low level performance stats like CPU and Mem usage).
I probably just need to read up more on SNMP and MIB's.
However, has anyone done SNMP agent monitoring with OpenSTA or any other test tools? Or does anyone know of an SNMP agent for solaris that will give me this info?
Thats what most of them are! Because SNMP is used for managing devices across a network eg setting up thresholds for various device properties and if they breach the threshold a response can be sent (trapped) by a network management application. A good book is "A practical guide to SNMPv3 and Network Management" It's worth it especially as OpenSTA is free. However SNMP manages 9 MIB groups system, interfaces, at, ip, icmp, tcp, udp, egp and snmp. most of these are network protocol's that you can monitor. System gives u basic detail about the machine/device you want to monitor, Interfaces gives info about the types of cards/devces attached to your machine. What I would do is use something like the rstat daemon for monitoring basic stuff on the solaris machine (ask a unix guy) and monitor that on your test machine. You can do this by using a free remote monitor like VNU that is very good. Do a google search for VNU.
