 |
|
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.

/usr/bin/rrdtool create \

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!

GOOD LORD I read this entire thread thinking "There is no way in hell I'm running the poller as root why the hell has no one used 'fping' when the script is called 'fping'" and here I am, last page, the first person with the necessary level of intelligence. Installed and it worked straight off with no problems. THANK YOU!

I have imported the template and the ss_fping script. Am I missing something?

Got the same problem over here. I do not get anything.
I've commented line 12. (edited it to: //error_reporting(0);
This enables errors php is giving.
When I run the command it gives an error:
Fatal error: Call to undefined function read_config_option() in /usr/share/cacti/site/scripts/ss_fping.php on line 42.
This script seems to be old and some functions it needs do not exist in the included files (seems correct, because these are in lib/functions.php).
So I traced the function calls for read_config_option() in ss_fping.php.
I commented the rows by adding two slashes for the row and manually typed a value for the variable.
scripts/ss_fping.php line 42:
| Code: |
$script_timeout = 10;
$ping_timeout = 5;
// $script_timeout = read_config_option("script_timeout");
// $ping_timeout = read_config_option("ping_timeout");
|
There was also a function call at line 100. I replaced this call by a variable;
scripts/ss_fping.php line 100:
| Code: |
$i = 0;
while ($i < $ping_sweeps) {
$result = $ping->ping(AVAIL_PING,
$method,
$ping_timeout,
1);
|
Now, when I run the command: sudo /usr/bin/php ss_fping.php localhost
I get:
min:0.0600 avg:0.0683 max:0.1100 dev:0.0186 loss:0.0000
So this fixes my script problem. I've imported the latest script a few post above this one. But i'm not getting any graphs. I will debug for a while and report later.
I've found out cacti doesn't like the template:

I've found the solution by using my modified php script (see previous post) and using the basic template in the start post of this topic.
When you get results by runnig the script through the command line, you should be able to get stats in cacti by using the correct template.

Thanks ! But in my case, the script works.

Hello,
I'm new in this forum and I just started to use this amazing template (version 2.1). To solve the error:
ERROR: the RRD does not contain an RRA matching the chosen CF
you have to add the "LAST" Consolidation Function to the rrd files. Cacti 0.8.7 defaults to only "AVERAGE" and "MAX". You can achieve this in two ways:
1) In "Data Sources" -> RRAs, modify the available RRAs adding LAST consolidation function. In this way you change the default.
2) In "Data Sources" -> RRAs, adds 5 RRAs cloning the existing and add LAST consolidation function as above, and in the Data Template modify "Associated RRA's" to use the new created RRAs.
Before the graphs works, you need to remove the rrd files and wait the poller...
