I have configured an alertmanager and it sends alerts properly But it does not send resolved email. I have tried different amount of time for resovled timeout but it did not work
here is my configuration I am running alertmanager and prometheus on centos 8 & 7 and using latest version of alertmanager I use alerts for many things like service status and os maintenance
---------define sender configuration----------------------
global:
smtp_from: '[email protected]'
smtp_smarthost: 'mail.server:25'
smtp_auth_username: ''
smtp_auth_password: 'mypassword'
smtp_auth_identity: 'username'
smtp_require_tls: false
smtp_ssl_auth_enable: false
resolve_timeout: 1m
------------define default route for alerts that do not match sub children-------
route:
receiver: 'default-receiver'
group_wait: 1m
group_interval: 1m
repeat_interval: 1h
group_by: [cluster, alertname]
--------define sub route-----------------------------------
routes:
------define second sub route-----------------------------
receiver: 'devops'
group_by: [product, environment]
matchers:
service="DevOps"
------------define receivers email addresses-----------------
receivers:
name: 'devops'
email_configs:
to: '[email protected]'
to: '[email protected]'
to: '[email protected]'
send_resolved: true
name: 'default-receiver'
email_configs:
to: '[email protected]'
send_resolved: true
-------
it is also one of my rules:
--------
groups:
name: DISK USAGE
rules:
alert: DEV-DISK-USAGE-CRITICAL-196
expr: 100 - ((node_filesystem_avail_bytes{instance="192.168.100.200:9100",job="Docker-node-exporter",mountpoint="/",fstype!="rootfs"} * 100) / node_filesystem_size_bytes{instance="192.168.100.200:9100",job="Docker-node-exporter",mountpoint="/",fstype!="rootfs"}) > 80
for: 5m
labels:
service: "DevOps"
annotations:
summary: "Server 200 DISK USAGE CRITICAL"
description: "disk usage is critical"
