Some rrd not updated anymore

[crieur.com]

Hi all

I have a strange behavior :
Cacti just stop updating some rrd one day ago, the polling is still done.

In the logs when I use the DEBUG level I see

1) the polling command through CMD
2) then the SQL Exec: "insert into poller_output
3) no rrdtool update after that


Only 10 rrd are behaving like that , the others are ok...

Anyone ?

Run poller.php from a command line and look for RRDupdate issue. Also, when the poller is finished, look to see if the poller_output table is empty.

Report your findings here.

I ran the poller in cmdline mode and there is no " rrdtoo update " for these rrd and the poller_output table contains 114542 rows

I must say that I use a poller every minute with a patch found here to enable a poller frequency of 1 min

(and PIA Arch also and 3 plugins)

Bye

Increase your PHP memory in php.ini to 128MBytes. Then run the following attached script. Place it in your Cacti root directory.

Seems to work ! My graph are back but the script is still running...(launch an hour ago at least)

We'll see tomorrow

Thanks again

Thank you "TheWitness"

Is it a bug or is it due to something I've done ?

I was obliged to stop the script after may hours running (cause someone wanted to sleep and I had to shut down my workstation

What I meant is, will I have to use this script again in the future or is it ok ?


Bye and again thanks

No, this is likely due to insufficient memory from PHP to process all of the RRD files. With the higher memory setting, you should not experience this problem again.
