VictoriaMetrics 集成karma
以前有介绍过karma，以下是一个集成，实际上这个肯定是可以跑通的，因为依赖的都是alertmanager这个是都兼容的

- 配置
主要包含vmagent,vmauth,vmalert.alertmanager,karma
vmagent(就是prometheus 的配置)
global:
scrape_interval: 1s
evaluation_interval: 1s
scrape_configs:
- job_name: 'prometheus'
static_configs:
- targets: ['prometheus:9090']
- job_name: 'vminsert'
static_configs:
- targets: ['vminsert:8480']
- job_name: 'vmselect'
static_configs:
- targets: ['vmselect:8481']
- job_name: 'vmstorage'
static_configs:
- targets: ['vmstorage:8482']
vmauth
users:
- username: "dalong-select-account-1"
password: "dalong"
url_prefix: "http://vmselect:8481/select/1/prometheus"
- username: "dalong-insert-account-1"
password: "dalong"
url_prefix: "http://vminsert:8480/insert/1/prometheus"
vmalert 主要是rules
groups:
- name: groupGorSingleAlert
rules:
- alert: VMRows
for: 10s
expr: vm_rows > 0
labels:
label: bar
host: "{{ $labels.instance }}"
annotations:
summary: "{{ $value|humanize }}"
description: "{{$labels}}"
- name: TestGroup
rules:
- alert: Conns
expr: sum(vm_tcplistener_conns) by(instance) > 1
annotations:
summary: "Too high connection number for {{$labels.instance}}"
description: "It is {{ $value }} connections for {{$labels.instance}}"
- alert: ExampleAlertAlwaysFiring
expr: sum by(job)
(up == 1)
alertmanager
global:
resolve_timeout: 30s
route:
group_by: ["alertname"]
group_wait: 5s
group_interval: 10s
repeat_interval: 999h
receiver: "default"
routes:
- receiver: "default"
group_by: []
match_re:
alertname: .*
continue: true
- receiver: "pagination"
group_by: ["alertname", "instance"]
match_re:
alertname: Pagination Test
continue: false
- receiver: "by-cluster-service"
group_by: ["alertname", "cluster", "service"]
match_re:
alertname: .*
continue: true
- receiver: "by-name"
group_by: [alertname]
match_re:
alertname: .*
continue: true
- receiver: "by-cluster"
group_by: [cluster]
match_re:
alertname: .*
continue: true
inhibit_rules:
- source_match:
severity: "critical"
target_match:
severity: "warning"
# Apply inhibition if the alertname and cluster is the same in both
equal: ["alertname", "cluster"]
receivers:
- name: "default"
- name: "pagination"
- name: "by-cluster-service"
- name: "by-name"
- name: "by-cluster"
karma
alertdashboard
- 启动
docker-compose up -d
- 一些说明
为了处理slice 报警使用了kthxbye
效果
