Re: [Ganglia-general] log file

No, there are no "log" files for Ganglia other than the info contained in the rrd files.
It is possible however for you to create your own log of the system by periodically
extracting the information from the ganglia data stream and inputing the result
into a database somewhere outside of ganglia. There is a ganglia python command
line client that would be perfect for this that allows the user to extract plain text
metrics or the actual XML formated text from the ganglia monitoring system.

Hi Steven,
One more question if you could help me in that. On the ganglia Cluser Report page, I see "Avg Load" for 1m, 5m, 15m. Are these values also got logged somewhere? I believe ganglia must be keeping them somewhere other than rrd files. I was looking into the rrd files and they are not updated for last few months. That means the values for "Avg Load" must be coming from and logged into some other file.
If you have any idea about it, please let me know.
Thanks,
Abhi.

In Ganglia the rrd files allow you to look at data from now back an hour, or from now back a day,
or now back a week, or now back a year. What it does not allow you to do is look for data for
a specific time period in the past (i.e. last Tuesday from 3PM to 4PM). This is just not possible
with the way the rrd database works.

HI Steven,
I am looking for the total memory and cpu load either per day or atleast per week. I believe this is the standard metrics for ganglia. Isn't it? If so, are these values present in rrd files?
Thanks,
Abhi.

The rrd files are the only "logs" unless you count the ones for apache or whatever web you are using to serve the ganglia web frontend pages.
When you say "cluster usage" what specifically are you referring to? User that have been logged in or running jobs? Or are you referring to the memory or cpu load of the cluster? If the details you are looking for are not one of the standard metrics tracked by ganglia or a custom metric you have created/added to the system then it will not be available. -----Original Message-----

I want to see the cluster usage in last few months. Is there any way I could see that? Thanks, Abhi. ------------------------------------------------------------------------------ Come build with us!
