Inconsistent Number of Data Records across 5mins Polling Interval #12

Open SriRamya-M opened 6 years ago

SriRamya-M commented 6 years ago

We are currently setting up Cacti (Version 1.1.28) with Mirage plugin in our environment. Everything working well except we observed that number of data records collected across the 5 minutes interval is inconsistent. Here are summary of our observations from mirage log:

Timestamp 12:20 12:25 12:30 12:35 12:40 12:45 12:50 12:55 13:00 13:05
Records 618 630 80 630 630 23 630 630 296 501

Few additional details:

  1. Poller (spine) is set to poll every 5min with “Script and Script Server Timeout Value” set to 5 mins as well
  2. No errors regarding polling in cacti.log

Any reason for above observation, Any suggestion how to debug this? Thanks.

Hi

Can you check the cacti.log for your polling stats?

Hi, The below are the stats I have took from cacti.log 2018/03/20 08:55:03 - SYSTEM STATS: Time:2.2974 Method:spine Processes:2 Threads:1 Hosts:13 HostsPerProcess:7 DataSources:628 RRDsProcessed:171 2018/03/20 08:55:03 - SYSTEM THOLD STATS: Time:0.0237 Tholds:1 TotalDevices:13 DownDevices:0 NewDownDevices: 2018/03/20 08:55:04 - SYSTEM MONITOR STATS: Time:0.08 Reboots:0 DownDevices:0 Notifications:0 Purges:0

Although there are no down devices in first two slots,the no of rrds is inconsistent.

I could also see below errors/warns in addition to stats 2018/03/20 09:05:01 - POLLER: Poller[1] WARNING: Poller Output Table not Empty.
