[mrtg] MRTG Graphs not Refreshing

Have you checked that you are not looking at old graphs, being delivered 
from a web proxy, cache, and such?
In other words: check the timestamps of the actual image files.

Better yet, delete those. MRTG will recreate them all.

After deleting the graphs (daily, weekly, monthly, yearly) and before MRTG 
runs again: are they still visible on the web page?  If yes, then you are 
probably looking at old files, cached information, not at fresh information 
from your server.  In that case, don't focus on MRTG. Have a good look at 
your caching proxy, your web browser, and such.

Subject: [mrtg] MRTG Graphs not Refreshing

Hi all,

I just joined this community! Been troubleshooting this issue for a few days 
now and needed some professional help. Thanks in advance, to any suggesting 
you guys may provide!

A Linux server was configured for MRTG using cfgmaker more than a year ago. 
It continued to work as desired until earlier year.

There are some graphs being polled from a router that are not updating. The 
last refresh date for each graph that is not refreshing is unique and within 
the last few months. The strange is, there are graphs that are not updating 
and those that are updating from the same router.

Please see the following:

Actions taken:

*         Restart crond, httpd and snmp services

*         Reload the Linux server

o   Strange thing happened here: Those graphs that have been static and not 
updating remained on the http page, those that were still dynamically 
updating were not showing anything until crond and httpd was restared.

Any help would be much appreciated!!

Update: Graphs are updating now but the "Daily Graph," others are remaining 
static. Also, the last update date has not updated.

Mohammad Hassan
