It's in the poller tab on settings. I believe that threads only applies if you are using spine.

You set the cron entry just as shown in the default install... IOW "*/5" in the first field. Don't change the cron entry when moving to a 1 minute poller interval.

Is this setting right?

Yes, this is correct.

Witness, can you offer comment on how the 2x + rounding amount was chosen?

Thanks,

So, should I change cron to run only every 5 minutes? Well... there we have it. I changed cron to run every 5 minutes, and now everything looks good. No poller output table warnings, and no database errors. :) I had a quick look at the code in poller.php, and it appears to be very focused on either...

TheWitness wrote:look for multiple poller.php's running

Well, given that poller.php hangs for 5 minutes, and that cron is starting a poller.php every minute, by definition there will be multiple pollers running at the same time.

So, should I change cron to run only every 5 minutes?

Denny

Might this be the a source of the multiple poller issue?

I currently have cron set up for every minute, which I assumed was required for the 1 minute polling. Is this not the case?

On the data source keying issue, is there something that I can to do help diagnose this?

Thanks,

Denny

Do you have a double crontab issue? TheWitness No, just one crontab entry. However, I have noticed that poller.php will sometimes hang around for several (5) minutes. But not always. A bit of checking shows that this appears related to the poller output table problem. When the hung poller.php proce...

Thanks! I inserted the new versions of query_host_cpu.php and query_host_partitions.php. The number of errors is reduced. However, I am still receiving DB insert errors, and poller output table warnings: 10/26/2007 10:46:03 AM - SYSTEM STATS: Time:2.4737 Method:spine Processes:5 Threads:5 Hosts:6 Ho...

After upgrading to 0.8.7, I am experiencing serious poller problems with 1 minute polling. Php memory began at 128M. Increasing to 256M, and subsequently to 512M has had no effect. Both cmd.php and spine have the same result. Increasing/decreasing concurrent poller processes or threads seem to have ...

With the dawn comes light :) The number of rows is off by a factor of the polling interval. The minimum number of rows should be: Name Steps Rows Timespan Hourly (1 Minute Average) 1 60 3600 Daily (5 Minute Average) 5 288 86400 Weekly (30 Minute Average) 30 336 604800 Monthly (2 Hour Average) 120 37...

I also had this problem using 0.8.6j with the GS724T. I've never used anything earlier than 0.8.6j, but I can offer that the problem no longer happens with 0.8.7. Unfortunately, the GS724T doesn't support 64 bit counters. If you select 64 bit, then your values will always be 0. Btw, do you find that...

Ok, I've been beating my head on this... I'm trying to do 1 minute polling with 0.8.7. I am relatively new to cacti, had previously been using 0.8.6j. I started working on 1 minute polling a few days before 0.8.7 was released. :-? So, I've dumped everything and am starting afresh with 0.8.7. I have ...
