[SAGE] SUMMARY: Advice wanted on MRTG-like things

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

I'd like to thank the following people for sending their advice to my
query:

Adam Levin
James R Grinter
Alexios Zavras
Kurt Robinson

No one had the solution to easily gathering SNMP data from dynamic sources
(such as from large tables), but several people suggested sticking with my
custom gathering tools and feeding the data into rrdtool. I'll give that
a try.

Thank you.

Here's my original question:

    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.
