kapacitor-tasks

The Kapacitor task scripts, can be used with InfluxDB to monitor timeseries data. can be used with kapacitor-alarm.

note: these task scripts only test in kapacitor-1.5 and influxdb-1.7, some influx tag or field maybe different at old version.

How to use?

define the task

the database and retention policy can be changed by -dbrp option, or modify the line dbrp xxxx which in the tick script:

# kapacitor define cpu_usage -tick cpu/cpu_usage.tick

enable the task

after define task, you can enable the monitor:

# kapacitor enable cpu_usage

task list

cpu

cpu_usage.tick

disk

disk_bandwidth.tick
disk_iops.tick
disk_latency.tick
disk_used.tick

memory

memory/memory_used.tick

system

system_load.tick
system_process.tick
system_swap.tick

network

network_connect.tick
network_traffic.tick

memory

memcached_conn.tick
memcached_qps.tick

mongodb

mongodb_active.tick
mongodb_conn.tick
mongodb_qps.tick
mongodb_queued.tick

mysql

mysql_conn.tick
mysql_qps_detect.tick
mysql_qps.tick
mysql_slave.tick

redis

redis_conn.tick
redis_mem.tick
redis_qps.tick
redis_slave.tick

check tools

dependency

the following dependency packages should be installed:

perl-libwww-perl
perl-HTTP-Message
perl-DateTime
perl-JSON
perl-Data-Dumper

how to use?

the check_tools directory contains some useful utilities so that we can check custom timeseries data:

set_tick.sh     # define and enable kapacitor tasks in batch way
exec_parse.pl   # sample usage when you use the alert.exec() method
service_check.pl  
service_check.tick

the service_check.pl check the lastest system, mysql, redis and memcached items, then insert expire status to the "db"."autogen"."service_check". service_check.tick use the isTimeExpire filed to determine whether the service is alive or dead, or missing lastest data.

service_check.pl can be run as crontab jobs, and the period time in service_check.tick should be greater than crontab interval time.

define and enable kapacitor tasks

$ cd kapacitor-tasks
$ bash check_tools/set_tick.sh -d -e
