Gopal, If your check the poller cache for this device, it's likely empty. This is an issue that was discovered and fixed in the upcoming 1.2.20 release which is delayed due to some last minute scalability enhancements to the security algorithms. The short term work around it to repopulate the poller cache from device edit. Mark is saying April 2nd for release as he wants people testing and reporting back. It's going to be a big release from my perspective. Larry |

Thanks Larry , but in fact I checked the poller_cache and it was there , and in fact out of 20 graphs 15 were being populated and rest 5 were nan I forgot to mention this in ticket . so what I was expecting like in spine we should have those 15 graphs' items output but that is what was also missing . so any pointers for this like why it happened and what I could check next time . regarding that logs not coming in cacti , i removed those graphs and created new ones and they are being populated .Hope 1.2.20 fixes it . Best Regards, |

Maybe @bmfmancini might have some tips. There was a bug he identified in lib/poller.php that was blocking proper replication. Also check the orphan column in data_local. If it 1, it was removed due to a reached event. |
|
yes Larry I checked for orphan column in remote db which is used for polling as well as central db , i do not find value 1 . I checked in local_data , but this is a trouble I think as this happened twice with me .on central db i see 32 rows for that device (as i informed like for 3 non working graphs I created fresh graphs) but on remote db i see only 29 rows in local_data . PFB output from remote db MariaDB [cacti]> select * from data_local where host_id=323; now on central db MariaDB [cacti]> select * from data_local where host_id=323; anyway let me do a sync and then I update you . |
|
I'm guessing that that settings is not replicated to the remote. I'm going to check, but on the local, it's working well (for one device at least). Checking a few more things.

Okay, digging in deeper, found that when you set a device into debug mode, that setting choice is not replicated to the remote data collectors. I'm going to be making an update here shortly, but I have to check some additional areas where this needs to happen. |

Describe the bug
Hi Team ,
in fact one of my device was not getting populated in cacti 1.2.18 in a multi poller environment . So I thought of lets see what do we get in spine debug as we are using spine and thought of running the spine in verbose mode ie -V=5 that is debug .
But to my surprise i do not see any polling for that device . yes the spine is 1.2.17 as it is evident in the below mentioned logs of spine run as well .
./spine -f=323 -l=323 -R -S -V=5

so my first question is why spine is not in debug mode like polling for this OID and this is value , this OID and that is value but very often I do not see that , so is there any problem with code or what ??
now I enabled the device debug for id=323 but i do not see in the logs for this device , in fact any log .
user@cacti-remote-poller:
/log $ grep -i 'device[323]' cacti.log/log $user@cacti-remote-poller:
so I know it is a multi poller environment , so yes , i checked for logs on remote poller and yes I checked like whether the device is in debug mode on that poller or not so , i checked in web gui of remote and i saw yes the debug for that device is propagated from main poller to remote poller .
but even then I am not able to see the logs . in fact many times it happens like device is down or the port or iterface is down and cacti polls for a number of times and then stops but here device is up and so is the interface but why no logs ??
