Hi,
I need help in this alert test.
This is the alert rule I have,
- alert: ServiceMemoryUsage90Percent
expr:
sum(container_memory_usage_bytes{job="cadvisor",container_label_io_rancher_stack_name!="",
image=~"rancher.*"}) by (container_label_io_rancher_stack_name, instance,
dns_name) /1024/1024/1024 *100 > 90
for: 5m
labels:
severity: Critical
alert_owner: alerts-infra
annotations:
description: "Service memory has been at over 90% for 1 minute. Service: {{
$labels.container_label_io_rancher_stack_name }}, DnsName: {{
$labels.dns_name }}. \n"
I am trying to write a test for this,
tests:
# Infra Alert Tests
- input_series:
- series:
'container_memory_usage_bytes{job="cadvisor",container_label_io_rancher_stack_name="network-service",image="rancher.test"}'
values: '0 100000000 0 100000000 100000000'
alert_rule_test:
- alertname: ServiceMemoryUsage90Percent
# eval_time: 5m
exp_alerts:
- exp_labels:
alertname: ServiceMemoryUsage90Percent
severity: Critical
alert_owner: alerts-infra
exp_annotations:
description: "Service memory has been at over 90% for 1 minute. Service:
(), DnsName: ()."
But I am always getting ,
*Unit Testing: tests/infra_db_alerts-tests.yml FAILED: alertname:
ServiceMemoryUsage90Percent, time: 0s, exp:[ 0:
Labels:{alert_owner="alerts-infra",
alertname="ServiceMemoryUsage90Percent", severity="Critical"}
Annotations:{description="Service memory has been at over 90% for 1 minute.
Service: (), DnsName: ()."} ], got:[]*
I tried many options in alert rule testing. But nothing helped.
Any help on this please?
not sure why I am getting got as empty. And always alert is getting
triggered even if I keep input series value as 0.
