looks like mrtg is taking more than 5 minutes. I have increased fork to 16 but that doesn't help

Can you try increasing it higher?

The only other thing I can think of would be for you to follow this KB article and comment out the ports in the MRTG configs that you don't want polled:

OR you could look at offloading MRTG:

I asked before if MRTG could be offloaded and I was told that couldn't be done

I increased the forks to 160. i know I crazy number. still not perfect

the port approach is not sustainable model. I dont think that will work for me

In the latest version of the Network Switch / Router wizard (2.3.2, you can verify by going to Admin > Manage Config Wizards) it will create a /etc/mrtg/conf.d/DEVICE_PORT.cfg for each port that you select (it will not add all or query all by default).

You would need to remove your current single config (/etc/mrtg/conf.d/DEVICE.cfg) for the devices and re-run the the wizard and that should speed things up if you don't monitor every port on each device.

the link you sent me lead me to troubleshot this further and found that a .cfg file was creating the whole problem. removed that .cfg file and things are running perfectly since yesterday.

can't believe a file could create such a big problem. my MRTGs are finishing within 1 minute.

thanks a lot for the help. close the ticket
