RRD Updates can become disabled when saving performance options

[bmfmancini]

Hey Guys

Testing 1.2.16 I found that after I changed the Maximum records field in the performance tab
graphs from the remote poller stopped

Did the following troubleshooting

• Ran spine manually in read-only mode showed the devices and SNMP info came in properly
• Forced a boost update to clear the table which did not help
• No errors in cacti log
• Did a Poller sync first time it worked for about 4 minutes then stopped forced another sync working fine for now

Was able to re-produce this again changed max records and graphs broke again
Poller sync fixes the issue again

Need more specific info @bmfmancini. Screen shot?

[TheWitness]

Of status page under utilities.

[bmfmancini]

Changed max rows from 5k to 10k

Each time I edit the max rows field the graphs stop working until poller sync

[bmfmancini]

@TheWitness this is what my boost status page looks like

this is a small lab instance so not a whole lot of devices
when the issue is happening boost appears to run fine no errors or anything

Well, make your argument length longer. What is your clients max allowed packet? Agree, small system.

[bmfmancini]

Let me check on the max packet

This happens right after you make a change even before boost runs if that helps

Main poller

Remote

[TheWitness]

Since it the lab, set it large, put poller_boost.php into debug and then run

php -q poller_boost.php --force

Then share the log to the developers email.

Sure I am building another lab just to be sure As well to reproduce it on another system

Well, I had to remind myself how this thing works. That number should be in this millions, and the argument length about 20k. Then at 20k data sources, assuming a poller interval of 5 minutes. Let's say you want to flush the cache every hour, the max records should be about 12 * 20k. Flushing will only happen once an hour, and it'll go quickly.

Here is the setting on my little sanbox of about 70 hosts. Remote poller has ZERO CORRELATION to those settings. So, you are confused.
