SAA Basic not graphing but SAA Jitter Is.

[Meep]

Hi All,

I'm a long time user of Cacti and a long time reader of these forums but this is my first post as for once I can't find someone who's already asked the same question as me!

As the title says I'm having a bit of trouble with some of my SAA Basic graphs on a Cisco router. The SAA Jitter for those devices is still graphing and the SAA Basics are even graphing on the backup box so I think it's likely a simple fault on the primary box but for the life of me I can't find it!

The debug for the graph is as follows:

Code: Select all

/usr/bin/rrdtool graph - \

RRDTool Says:
OK

The verbose output of the query on the device is:

From my knowledge of Cacti as the graph debug is ok it's not a write problem and I've checked the probes on the Cisco routers and they are running and generating the RTT information (obviously as the jitter is graphing).

I'm not sure if it's related but when I try and create another SAA basic graph for the device's as soon as I select "SAA BASIC STATISTICS" the data query greys out and the tick box disappears. Is it possible the query has got corrupted?

Thank you for you help in advance and let me know if you need any more information.

I thought it might be helpful if I uploaded a screenshot of the problem so here one is!

I've followed the guide and can see nothing wrong except that when I did

Code: Select all

rrdtool fetch <rrd file> AVERAGE

I got all NANs.

I then followed the next step of

rrdtool info <rrd file>

but according to that there is information for rtt

Code: Select all

ds[rtt].type = "GAUGE"
ds[rtt].minimal_heartbeat = 600
ds[rtt].min = 0.0000000000e+00
ds[rtt].max = 4.9990000000e+03
ds[rtt].last_ds = "31"
ds[rtt].value = 6.2000000000e+02
ds[rtt].unknown_sec = 0

Am i looking at the wrong information? What was also weird was that when i checked that information on the back up box it's data is different:

Code: Select all

ds[rtt].type = "GAUGE"
ds[rtt].minimal_heartbeat = 600
ds[rtt].min = 0.0000000000e+00
ds[rtt].max = 4.9990000000e+03
ds[rtt].last_ds = "UNKN"
ds[rtt].value = 0.0000000000e+00
ds[rtt].unknown_sec = 50

This problem seems like a real head scratcher to me, any help would be greatly appreciated.

hello, newbie question :
I try to understand jitter graphs and I don't understand meanings of graphs

could someone explain me
+source -> destination
+DEST -> source
-source -> dest
- dest -> source

and the green line

thanks you !

Hey, I have the same doubt!

Can't really understand this graph. How is it related with jitter time/threshold of 30 miliseconds?

Anyone?

Thank you!!!
