[SAGE] Advice wanted on MRTG-like things

[John P Speno <speno@isc.upenn.edu>]

Please send all response directly to me. I will post a SUMMARY of my
findings back to this list.

I'm looking for a tool to graph SNMP collectible data.  I'm aware of the
names of many such open source tools and several commercial applications,
e.g. mrtg, cricket, and concord network health.  However, what I'm not
certain of is if they can "easily" handle SNMP tables.

For example, I wanted to collect data from several Juniper routers's
firewall table (.1.3.6.1.4.1.2636.3.5.1). That table has five columns:
Filter, Counter, Type, Packets and Bytes. The number of rows is the number
of filters. In my case, that's about 1000 rows.

So, I'd like to tell my tool the OID of the table and what columns I'd like
to poll and have it produce a graph or (1000) graphs of the results over
time. In this case, graphing the number of bytes per counter.

Now, I guess I could fake it by configuring all 1000 things that I want
polled and graph in some of these tools, but I'd rather not have to do that
each time I add new rows (there could easily be 2000 rows tomorrow.)

Until I find something else that I like, I'm using python and pysnmp to
collect the data myself and dump it into tab delimited files which are
fed to excel or grace to generate graphs as needed.

I'll consider open source or commercial solutions as we are in the process
of re-evaluating all of our NMS tools at the moment.

Thanks.
