rra not written or WARNING: Poller Output Table not Empty.

[zez3]

I got this "WARNING: Poller Output Table not Empty" after the migration 0.8.8_h-1 -> 1.0.0-1 Currently running 1.0.4-1 but the issue is not yet fixed.

Same issue described here: http://forums.cacti.net/viewtopic.php?f=21&t=36706 I tried to repopullate, change the polling time and cron with no success.

One strange thing that I saw is that after the migration I have a second Data source Profile

You need to dump you Cacti database and email it. However, before you do that, please run:

select * from poller_output;

between poller runs and post here.

[zez3]

I guess you haven't checked the link that I posted above but anyhow here is the output:

[cigamit]

for the 4 data input methods, can you please dump the contents of the poller_item table?

select * from poller_item when local_data_id in (10,11,9,8);

[zez3]

here you go:

MariaDB [cacti]> select * from poller_item where local_data_id in (10,11,9,8);

Hmm. Can you provide a screen shots of the Data Input Method of one of these in the 'Edit' mode so I can see the field mappings. Also, the same Data Template for the Data Input method.

[zez3]

here are some prt-screens with my config Let me know if need something else Thanks

[cigamit]

So, you have no data template associated with these? It's a full manual process from data input method all the way to graph. I figured no one in their right mind would ever do that since like Cacti 0.6. This is why it was never tested. Can you just confirm that?

[zez3]

Yes, this was a manually created graph, no template was used indeed.

[cigamit]

This should be working now. You will have to remove the corrupt graphs though.

[rcmcronny]

i have had this issue also. i tdid a new upgrade from 0.8.8h to 1.1.0 and created also a new graph, but this issue persists. I've had post in the forum (http://forums.cacti.net/viewtopic.php?f=2&t=56908) but no response, its exact the same issue as here mentioned. I have now assigned the data queries and graphs to 1 device, so its not device and template less These graphs worked with 0.x cactis without any issues.

@zez3 does ist work for you with 1.1.0 ?

Thanks Ronny

[zez3]

Nope, same here, not working. Tried recreating the graph and data sources.

I saw a few red strange graph.php related errors after the upgrade but I did not managed to save them. I'll try to somehow get them from and archive or rerun the install process.

I think this ticket should be reoppened.

So here is what I get after upgrading to the lastest version:

Looking at only the SQL errors, please update to the latest lib/auth.php and see if those go away.

[cigamit]

I was speaking more of the SQL error when viewing the Tree. I'm still not certain of the other issue.

[cigamit]

When you goto the poller item table, there is a column 'rrd_num'. For you example(s), what is that value? The reason that I ask is that you are specifying two outputs for your Data Input Method, but only using one of them in the graph. I'm not sure that will work. We expect that the two output values will be used, in other words, your output should look like "CPU_temp:nn GPU_temp:mm", and that you will have two data sources in your Data template: CPU_temp and GPU_temp. Your RRDfile also contains a number of data sources that are not in the Data Template.

[cigamit]

No feedback.

Took you long enough. But it's finally fixed. Version 1.1.13 has fixes this issue

[majed17]

so i get this on 1.2.x, while on another 1.2.6 cacti there is no such problem with the same device...

i tried queering the device and saving and it logs that is reindexing but then after a while the same thing repeats! what is this about?

[cigamit]

@majed17, old comment. It's likely due to your Nexus timing out with a small snmp (500ms) timeout. You have to watch the MaxOID's per get request. As you increase that number, the device will take longer to respond. On some of the old Cisco switches, if you got in the 20's, thing became very unstable.

[majed17]

wow you nailed it...i was so deceived by the thought that i have 2 nexuses of the same model so it must be the desert plant again sucking up all the water .. but then i realized, the other nexus has a newer ios, so it's timeout must be fixed.. and now almost a day after reducing the threads and processes to 1, the affected device shut up!

[sirjana]

I am getting Cacti log error as: 1/03/2020 12:18:39 PM - CMDPHP: Poller[0] WARNING: SNMP Get Timeout for Host

POLLER: Poller[0] WARNING: Poller Output Table not Empty. Issues Found: 274636, Data Sources: traffic_in(DS[24]), traffic_out(DS[24]),

Due to this all graph seems broken and I tried on different server and working fine. I have increased The Maximum SNMP OID's Per SNMP Get Request and snmp timeout but it's still not working. Any idea? please help

[netniV]

It would suggest that Cacti can't retrieve the data from that device for that interface. If that is true, disable the source and everything else should be working. Whilst that is disabled, check and verify why it's not presenting itself using the snmpwalk command line tools from the cacti server.

[sirjana]

Thank you for the comment @netniV. snmpwalk is working fine and data can be query but there is break between graph on certain interval.

[netniV]

Then that would suggest either the device is getting too busy to respond at that time or your server is

[sirjana]

I'm also trying to reduce unnecessary hosts. Lets see this will solve the problem. But, What might be the possible solution for such error? WARNING: Poller Output Table not Empty. Issues Found

[netniV]

Because something didn’t get polled either a crash or too many items or non responsiveness from an endpoint.
