Icinga2+Influxdb+Grafana搭建
注:可不要icingaweb2(即無icinga2頁面),Icinga2要求2.5版本以上
不過安裝icingaweb2可友善排錯,步驟略,需要php和mysql
icinga2下載下傳網址:http://packages.icinga.org/epel/
influxdb下載下傳網址:https://dl.influxdata.com/influxdb/releases/influxdb-1.3.6.x86_64.rpm
Grafana下載下傳網址:https://s3-us-west-2.amazonaws.com/grafana-releases/release/grafana-4.5.2-1.x86_64.rpm
Icinga2安裝步驟:
需要的包:libboost_system1、libboost_thread1、libboost_regex1、boost-license1、libboost_program_options1、icinga2、icinga2-bin、icinga2-common、icingacli、nagios-plugins
安裝httpd:
# yum install httpd
額外包:fping、perl-NET-SNMP、perl-Crypt-DES (需先下載下傳好)
# rpm -i libboost* boost-license (需先下載下傳好)
# rpm -i icinga2* (需先下載下傳好)
# rpm -i perl-Crypt-DES perl-NET-SNMP fping perl-Digest-SHA1 perl-Digest-HMACperl-Socket6
# rpm -i nagios-plugins-1.4.16-1.el6.rf.x86_64.rpm
# chkconfig icinga2 --level 35 on
Influxdb安裝步驟:
# rpm -i influxdb-1.3.6.x86_64.rpm (端口8086)
配置檔案路徑:/etc/influxdb/influxdb.conf
資料存放路徑:/var/lib/influxdb/data
日志路徑:/var/log/influxdb/
# service influxdb start
# chkconfig influxdb --level 35 on
# influx
> create database icinga2;
> create user icinga2 with password 'xxxx';
> grant all on icinga2 to icinga2;
>quit
influxdb預設保留資料為168小時(即7天),調整為1年指令:
> show retention policies on icinga2; (檢視保留政策)
> alter retention policy "autogen" on "icinga2" duration 365d default; (對已有政策進行修改)
# vi /etc/icinga2/features-enabled/influxdb.conf
library "perfdata"
object InfluxdbWriter "influxdb" {
host = "127.0.0.1"
port = 8086
database = "icinga2"
host_template = {
measurement = "$host.check_command$"
tags = {
hostname = "$host.name$"
}
}
service_template = {
measurement = "$service.check_command$"
service = "$service.name$"
}
enable_send_thresholds = true
enable_send_metadata = true
}
:wq
# icinga2 feature enable influxdb
# service icinga2 restart
Granfana安裝步驟:
# rpm -i grafana-4.5.2-1.x86_64.rpm (端口3000)
# service grafana-server start
# chkconfig grafana-server --level 35 on
通路http://ip:3000 預設使用者名、密碼均為admin
Data Sources:Name:icinga2(可改) Type:InfluxDB Url:http://ip:8086 Access:proxy Database:icinga2 User:icinga2 Password:xxxxx
具體icinga2配置和grafana面闆配置略
Grafana求多台伺服器平均值:
面闆——Graph——Metrics——Toggle Edit Mode:
SELECT mean("value") FROM "nrpe-mem" WHERE "hostname" =~ /shhu*/ and "metric" = 'Per' AND $timeFilter GROUP BY time($interval)
icinga influxdb面闆下載下傳網址:
<a href="https://grafana.com/dashboards/381/revisions">https://grafana.com/dashboards/381/revisions</a>
記得icinga2中需啟用ping4監控(該面闆依據ping4抓取伺服器名)
