cap on the graph

[krishol]

hello friends,

I have install Cacti 0.8.7e on ubuntu 10.04 server. Basically, I am monitoring Windows Application Server.

I have few database servers which are being backed up every day atleast once. And backup server is in the LAN. During the backup time, the traffic of my database server goes more then 80mb, which is obvious. But I really don't need to monitor that traffic. Because of the spike which comes at the time of backup, usual traffic is in the ground of the graph and have to zoom between two backup spike to monitor the normal traffic.

Now what I want is... Is there any option to put cap on the graph.. no matter what is the traffic, the graph will not be plotted more then the defined cap. Coz my usual traffic is not more then 2mb.

Is there any option like that..

Please help..

Thanks

Plesae define a maximum value for that data source. Do so using "rrdtool tune" on the given rrd file
R.

How can I do this..?? can you please give me some more hints.. coz I am new to cacti n new to ubuntu as well...

Personally, I'd just duplicate the existing interface graph template and then define a maximum for the vertical axis. you'll have to play around with the autoscaling options too.

Thanks guys,

As gandalf suggested me, I played with "RRDtool tune". I set max value as 10000 for traffic_in & traffic_out. This way I should not get more then 9.76Mb, right?? To monitor this, I copied a large file from network. But the graph plotted with the max value 47.34Mb.

Is there any value that I can't put less then that???

For the new user like me, I am gonna post what I did.
