OpsCenter sending alert emails or posting to a url never succeeded.

Anyone succeeded? Here is my setting for postUrl. == ubuntu@ip-172-31-55-130:/etc/opscenter/event-plugins$ more posturl.conf [posturl] enabled=1 # levels can be comma delimited list of any of the following: # DEBUG,INFO,WARN,ERROR,CRITICAL,ALERT # If left empty,

Slow query date without hour, minute,seconds.

The date column all look like below: The hour,minute,second: 00:00:00+. I really want to know when exactly(hour, minute) those slow queries happen. Does any one know how? Thanks so much! node_ip | date 172.31.44.252 | 2016-07-18 00:00:00+ 172.31.44.252 | 2016-07-18 00:00:00+ |

Sometimes, the Pending can change from 128 to 129, 125 etc. On Wed, Jul 13, 2016 at 10:32 AM, Yuan Fang wrote: > $nodetool tpstats > > ... > Pool Name Active Pending Completed > Blocked All time blocked > Native-Transport-Requests

Re: Is my cluster normal?

In addition, it seems the compaction is very often. It happens like every couple of seconds and one after one. It seems causing high load. On Wed, Jul 13, 2016 at 10:32 AM, Yuan Fang wrote: > $nodetool tpstats > > ... > Pool Name Active Pending

Is my cluster normal?

I have a cluster of 4 m4.xlarge nodes(4 cpus and 16 gb memory and 600GB ssd EBS). I can reach a cluster wide write requests of 30k/second and read request about 100/second. The cluster OS load constantly above 10. Are those normal? Thanks! Best, Yuan
