Oracle Messurements in HP OV 1

Not sure if this is what your looking for, but take a look at MRTG. It is a graphing app that has 1 hour/1 day/30 day/1 year graphs. It is designed for routers, but I customized it for my needs. Just do a web search for MRTG and you should find info on it.

Hi Blue,
what we want is to measure some internal Oracle parameters. We could read them out with SQL, but there is no way to display them in HP-OV. Only setting up events for notification. But we want to display them in our OV mostly graphical.
I don't know if MRTG is also for measuring SQL-Databases ?

No, I think MRTG only works with MIB's
Sorry I couldn't be more help,

Hi appi, well if you are looking for something to generate events based on tablespace util, listener up/down, etc...I have a script to take care of that, displaying messages through "opcmsg" in the OV's message browser.
But if you are looking for some reports, graphs,etc...you may use MRTG , NRG, whatever, but, making sure you have Oracle's snmp daemon properly configured and running of course.
Hope this helps, let me know if you want me to post the script, ok?

The best thing I could reccommend would be a DataBase HP Smart Plug In (DBSPI)
There's a DBSPI for Oracle and it does exactly what you need, probably a bit more as well.
There's nothing in there you couldn't duplicate yourself but doing so would take you a considerable time, months I would think.

Hi Mike,
that's right. We use DBSPI for logfilies and alarming, but we hope to find some informations how we can make historical views for fillments or memory-usage.
So I hope taht the script from vlan will help us straight foreward

Question about DBSPI:
I have SNMP alarms coming in and they are stored in an oracle DB. I have one alarm that is a minor alarm, but I would like to change it to critical if it starts coming in at so many per minute. I don't think it is possible with NNM. Is DBSPI capable of sending an alert if the oracle DB is populated with this alarm at a threshold?
Thanks,
Blue

No problem Appi, here it goes, there is a script and a conf file for it.
The DBSPI solution is great, but, is kind of expensive, at least for our budget right now.
Hope this helps,
