Ping possible with cmd.php - not with cactid?

[kwaH]

Hi,

it seems that many people have a problem creating graphs for measuring latency times with ping using the script ping.pl.

I am one of them.

After struggling for hours I have found out that using cmd.php to gather the data and do the 'rrdtool update' does work but trying the same with cactid does not!

I am using cacti 0.85a on a FreeBSD box. When I activate the cmd.php call in the crontab of user root everything works fine. When activating the call of cactid instead nothing happens at all.

I did 'cactid |grep ping' and could not find anything. It seems as if cactid does not even consider that it´s supposed to do something with the rrd.

I have checked the permissions and the paths and I´m really stuck here.

Anyone have an idea?

Cheers,

P.S.: the problem is only with "Unix Host - Ping". Everything SNMP related works fine!

After debugging the SQL queries I guess the reason for cactid not doing a ping is as follows:

cactid does use the host id to decide what devices to query or which information to gather.
The "ping' graphs that I had configured had a host entry of "none" and thus were not relevant for 'cactid'.

If I am right this would also mean that cactid can not be used to trigger *any* script based data collection that is not associated with a host.

So if you want to be able to do an icmp echo latency graph you are forced to use cmd.php - which on the other hand is not fast enough for hundreds of targets.

I might be mistaken but if I am not this kind of sucks.

Could somebody please comment on this?

i believe you are right, i spent a couple of hours yesterday trying to make cactid pick up some 'none' hosts (to run some perl scripts), and it just would not run the scripts (even though the logs showed that it was running them)... i changed to cmd.php and it worked instantly.

bit of a bummer.

Correct, cactid does not currently support non-host based data sources. Sorry. I have not implemented support for non-host based data source items.

Have you attempted updating the number of concurrent processes and using cmd.php. Also, have you followed the informational / how-to on speeding up cmd.php?

Please let me know.
