OSPF route graph

[MatsB]

I'm looking for way to graph total number of routes in OSPF. Anyone got a working OID that I can use?

The ipForward table should have something close...start with ".1.3.6.1.2.1.4.24.6" (may not be OSPF only)

Where you able to do an number of routes graph? I would very much want one myself :]

[MatsB]

Nope it didn't work

IP-FORWARD-MIB::inetCidrRouteNumber = No Such Object available on this agent at this OID

Please post a short snmpwalk output starting with ".1.3.6.1.2.1.4.24.6" and if you wish (and assuming its a Cisco router) look at the output from the router terminal session's output of "show ip ospf database summary"

If I walk .1.3.6.1.2.1.4.24.4 I get the whole routing table I think, same as with just .1.3.6.1.2.1.4.24, but there it starts with IP-FORWARD-MIB::ipCidrRouteNumber.0 = Gauge32: 5613, which I guess you could use to make a nice graph on overall routes in the router.

I made a template with the total connected routes from OSPF Area's. It graphs the number of routers and number of routes in all OSPF Area's the routes is participating in.
Exported using Cacti Version 0.8.6h

Moved to scripts and templates to attract more attention to this solution. Thank you for posting

unfortunately i cannot get this template cisco_ospf.xml to work on Cacti 0.8.7c. Can you export it for me/us?

I had to go into the "Data Queries" for "Cisco OSPF" and change:

path_cacti/resource/snmp_queries/cisco_ospf.xml

to

<path_cacti>/resource/snmp_queries/cisco_ospf.xml

as well as place cisco_ospf.xml into that directory after importing all the other xml files. Now a verbose query returns one area "0.0.0.0" which is my area 0.

I also had to delete the "Unit Grid Value (--unit/--y-grid)" value of 1, to nothing... rrdtool 1.2 didn't like that.

Graphs are now showing up fine...

Also... please note the "total routers" is the total number of Border routers injecting E1/E2 routes... not total number of routers, or even neighbors. I tried to find an OID for # of neighbor routers... but can't find one.
