Metric query
As a tenant administrator or an editor, use the Metric query type to fetch the performance metrics data from BMC Helix Operations Management or BMC Helix Continuous Optimization.
This query type uses the PromQL or MetricsQL syntax.
This query requires the following data:
Examples for BMC Helix Operations Management
Here are a few examples of the Metric query type to fetch data from BMC Helix Operations Management:
Use case | Query |
|---|---|
View the CPU utilization for a LINUX host, where the host name is hostA.bmc.com. | Utilization{hostname="hostA.bmc.com"} |
View the available filesystem space on a device for the root file system, where the host name is hostB.bmc.com. | AvailableSpace{hostname="hostB.bmc.com", entityName="root"} |
View the CPU utilization of the Kubernetes Namespace | label_replace({__name__="CPUUtilization",entityTypeId="K8S_NAMESPACE",entityName=~"$K8_Env@$Namespace"}, "Var1", "${1}", "entityName", "^.*@(.*)") |
View the sum of the aggregate data of the metric name MEMmemVMUsed. If you have any host name, this query will return the aggregate data for both the entity and the host name | sum_over_time({__name__="MEMmemVMUsed",entityId="954c01b0-ed43-4b50-8dcc-cce56ce91ea5:NT_MEMORY:NT_MEMORY",entityTypeId="NT_MEMORY"}[1h]) |
View the sum of data points for the metric MEMmemVMUsed | sum({__name__="MEMmemVMUsed",entityId="954c01b0-ed43-4b50-8dcc-cce56ce91ea5:NT_MEMORY:NT_MEMORY",entityTypeId="NT_MEMORY"}) |
Examples for BMC Helix Continuous Optimization
Here are a few examples of the Metric query type to fetch data from BMC Helix Continuous Optimization:
Use case | Query | Visualization type | Output panel |
|---|---|---|---|
View the memory utilization details for the Kubernetes cluster. | MEM_UTIL{enttype="sys:kubernetes:cluster", entname="$Cluster"} * 100 | Gauge |
|
View the pod usage within the Kubernetes cluster. | (SUM(KPOD_NUM{entname="$Cluster"})/ SUM(KPOD_NUM_MAX{entname="$Cluster"}))*100 | Gauge |
|
View the CPU and memory utilization details for Kubernetes nodes. |
| Table |
|
View the CPU usage trend for the Kubernetes cluster. |
| Time series |
