Re: rhq-users Digest, Vol 19, Issue 5

Sarat,

Thanks Heiko for your response. I guess, your solution should address my problem correctly. However, does RHQ support data trending purely based on the metrics that it collects ?

What else would you base it on?

For eg: Lets say we have a JMX attribute that reports the live transaction count, incremented everytime there's a transaction happen in a system. Can I use RHQ's collection and plotting techniques to identify peak traffic hour during a day ?

Yes. As the tx count is monotonically increasing, you need to mark it as "trendsup" in the plugin descriptor, which makes RHQ automatically compute a per minute value of if (first derivate by time). So you don't look at the original metric to see the peal, but at the per minute value.
