Hi @Ram D The explanation for the parameter is: The multiple of the queue capacity which can be configured
to allow a single user to acquire more resources. By default this is set to 1
which ensures that a single user can never take more than the queue's
configured capacity irrespective of how idle the cluster is. Value is specified
as a float. There are two queue parms capacity and max capacity. The max determines elasticity and it is at queue level. We have to adjust the user-limit-factor so that user can
leverage more than just the capacity. What it says is a user can use X number
of times the capacity of the queue within under max capacity. Hope this helps !

Hi @Fish Berh This explains why the alert is generated. You need to increase the space to stop these alerts.

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",

"display_name" : "Warning",

},
{
"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",

Hope this helps.
