Hi
@Fish Berh
The default alert configuration for disk_usage is set like the one below:
I believe the minimum free space is kicking in here. "AlertDefinition" : {
"cluster_name" : "xxxxxxxxxx",
"component_name" : "AMBARI_AGENT",
"description" : "This host-level alert is triggered if the amount of disk space used goes above specific thresholds. The default threshold values are 50% for WARNING and 80% for CRITICAL",
"enabled" : true,
"id" : 48,
"ignore_host" : false,
"interval" : 1,
"label" : "Host Disk Usage",
"name" : "ambari_agent_disk_usage",
"scope" : "HOST",
"service_name" : "AMBARI",
"source" : {
"parameters" : [
{
"name" : "minimum.free.space",
"description" : "The overall amount of free disk space left before an alert is triggered.",
"threshold" : "WARNING",
"units" : "bytes",
"display_name" : "Minimum Free Space",
"type" : "NUMERIC",
"value" : "5.0E9"
},
{
"name" : "percent.used.space.warning.threshold",
"description" : "The percent of disk space consumed before a warning is triggered.",
"threshold" : "WARNING",
"units" : "%",
"display_name" : "Warning",
"type" : "PERCENT",
"value" : “0.5”
},
{
"name" : "percent.free.space.critical.threshold",
"description" : "The percent of disk space consumed before a critical alert is triggered.",
"threshold" : "CRITICAL",
"units" : "%",
"display_name" : "Critical",
"type" : "PERCENT",
"value" : “0.8”
}
],
"path" : "alert_disk_space.py",
"type" : "SCRIPT"
}
}
}
Hope this helps.
