EDIT: Advanced Ping Template Version 1.3 for Cacti 0.8.6g

[DinSoft]

Hi all,

I have an unexplained behaviour in Catci with the advanced ping plugin:

I am in Vietnam, and I am pinging a host in Switzerland.

There is no way that the RTT is less than 300 ms. It is actually very often over 500 ms. This is why I changed the ping timeout setting from the default 500 ms to 1000 ms.

But, on the graph, it looks like there are RTTs of < 100ms (around 16:00 and 18:00 - 18:20)

How can this happen ?

(I also paste here cacti's log file, without the SNMP data I gather from another device since it is probably irrelevant)

I am getting inconsistent graphs using the Advanced Ping. I have a tcp ping to CNN on port 80 which doesn't graph anything but loss. I have other hosts like Yahoo and Google that graph just fine. I also have another graph that is not displaying anything.

Running from the command line to another host I get different results. Also, the data listed at the bottom of the graph doesn't seem to match the graph.

Thanks a lot for this Template it gave me the base to have Latency graphs inside my CACTI installation. I changed them a bit so that all Comments are visible and also that the "smoke" is visible in both directions max -> avg -> min.

I also changed the ss_fping.php so that it can run with a non privileged user, using the fping binary which has to be installed (this is better than using normal ping).

If your interested in this changed graph templates and the modified ss_fping.php I will attach the files exported from a CACTI version 0.8.6j to this post.

ATTENTION: I have seen an error in the exported graph TEMPLATE and changed the attachement (just of the 1 person which already downloaded it Please have a look at the version number of the file!
