Gaps on only one graph

abadaba · Post by **abadaba** » Mon Jun 12, 2006 5:41 pm

This problem only occurs on one graph. Its the traffic graph of my BEFSX41 linksys router. Every other graph works just fine, with no gaps whats so ever. Ive read everything there is too read on this forum about gaps. From changing the polling timeout, snmp timeout etc. To changing too 64 bit counter "my router doesnt support v2." I also have changed the SNMP timeout for this host from 500-1000-1500-2000, still same thing. So here is an attatchment of the file, and the debug output...

Being that its Linksys, I blame them. The fact that the gaps are seemingly quite regular really looks like a problem with their snmp.

Turn the logging level to medium or high and leave it that way for 30-60min. Watch the graph for gaps and then look in the log file if Cacti got any data from the router (I'm betting no). When it didn't recieve any data, did cacti think the router was down?

My log stays on medium...so i always have that data...I will post as an attatchment in about 45 mins. I have upgraded too the newest firmware on my router...so i hope it changes...

Anyone?

BSOD2600 · Post by **BSOD2600** » Mon Jun 12, 2006 7:31 pm

Look on your graph, is there a gap in data for 06:18? If so, then you've just found the likely cause. If not, keep monitoring your logs and look for other anomalies.

abadaba · Post by **abadaba** » Mon Jun 12, 2006 8:01 pm

Yeah there is a gap around 6:18...What can cause this?

I have noticed about every other 4th pole...Well like ever other 20min interval i get this error...

BSOD2600 · Post by **BSOD2600** » Mon Jun 12, 2006 10:18 pm

Looks like the router is creating spikes in the data which cacti is supressing. Download STG and monitor the bandwidth on your router for a while. Does it report data spikes too? If so, then there is your problem; the router.

Hrrrm how do i run that thing?

BSOD2600 · Post by **BSOD2600** » Tue Jun 13, 2006 1:16 am

Well since it defaults to 192.168.1.1, in theory all you need to do is open it up, allow it in your windows firewall and it graphs your routers traffic.

abadaba · Post by **abadaba** » Tue Jun 13, 2006 5:44 am

I get "error getting first OID Error:11"

EDIT:it says target 127.0.0.1

So change the target to your router... View-> settings.
