Re: [ceph-users] "Cannot get stat of OSD" in ceph.mgr.log upon enabling influx plugin

2018-02-20 Thread knawnd 
Ben, first of all thanks a lot for such quick reply! I appreciate a provided explanation and info on 
things to check!
I am new to all that that including InfluxDB that's why I used wrong influx cli to check if there 
are actual data is coming. But 
https://docs.influxdata.com/influxdb/v1.4/query_language/schema_exploration/ page helped to figure 
it out. So data is coming from ceph mgr node to influx if ssl and verify_ssl options are set to 
false. But it seems with self-signed certificate, ssl=true and verify_ssl=false data is not filling 
up InfluxDB database. I will try to apply your suggestions on debug to find out a source of the 
problem. But that is a different story.


Thanks again for your prompt and informative reply!

The 'cannot stat' messages are normal at startup, we see them also in
our working setup with mgr influx module.  Maybe they could be fixed
by delaying the module startup,  or having it check for some other
'all good' status but I haven't looked into it.  You should only be
seeing them when the mgr initially loads.

As far as not getting data, if the self-test works and outputs metrics
then the module is reading metrics ok from the mgr.  A few things you
could try:

- Check that the user you setup has rights to the destination
database, or admin rights to create database if you did not create and
setup beforehand
- Increase mgr debug and see if anything is showing up:  ceph tell
mgr.* injectargs '--debug_mgr 20'(this will be a lot of logging,
be sure to reset to 1/5 default)
- Check that your influx server is getting the traffic:   ' tcpdump -i
eth1 port 8086 and src host.example '

thanks,
Ben

Dear Ceph users,

I am trying to enable influx plugin for ceph following

The log spam was also recently reported as happening when OSDs are
down (https://tracker.ceph.com/issues/23017).  This is annoying, I've
just written a patch for that bug.

Re: [ceph-users] "Cannot get stat of OSD" in ceph.mgr.log upon enabling influx plugin

2018-02-19 Thread Benjeman Meekhof 
The 'cannot stat' messages are normal at startup, we see them also in
our working setup with mgr influx module.  Maybe they could be fixed
by delaying the module startup,  or having it check for some other
'all good' status but I haven't looked into it.  You should only be
seeing them when the mgr initially loads.

As far as not getting data, if the self-test works and outputs metrics
then the module is reading metrics ok from the mgr.  A few things you
could try:

- Check that the user you setup has rights to the destination
database, or admin rights to create database if you did not create and
setup beforehand
- Increase mgr debug and see if anything is showing up:  ceph tell
mgr.* injectargs '--debug_mgr 20'(this will be a lot of logging,
be sure to reset to 1/5 default)
- Check that your influx server is getting the traffic:   ' tcpdump -i
eth1 port 8086 and src host.example '

thanks,
Ben

Dear Ceph users,

I am trying to enable influx plugin for ceph following http://docs.ceph.com/docs/master/mgr/influx/

one of ceph mgr node (running on CentOS 7.4.1708) there are the following messages in

influxdb-1.4.2-1.x86_64 is installed on influxdb host with CentOS 7.4.1708.

I would appreciate any help on that issue.
