Sample JSON rules

Unless otherwise noted, all JSON rules are entered into the Rule Box in the Expert Mode template.

Kill App Example

When workflow name is “prod_ml_model” and duration > 2h then kill jobs with allocated_vcores >= 20 and queue != ‘sla_queue’

In Rule Box enter:

{
  "scope": "by_name",
  "target": "prod_ml_model",
  "type": "WORKFLOW",
  "user_metric": "duration",
  "compare": ">",
  "value": 7200000
}

In Action Box enter:

{
  "action": "kill_app",
  "max_vcores": 20,
  "not_in_queues": ["sla_queue"],
  "if_triggered": false
}
AutoActions rules, predefined templates vs expert mode

AutoActions demo package documentation is here.

Predefined templates cover a variety of jobs, yet they can lack the specificity or complexity you need for monitoring.

For instance, you can use the Rogue Application template to determine if jobs are using too much memory or vCore resources by alerting for jobs using more than 1 TB of memory. However, if you only want to know if only Map Reduce jobs are using > 1 TB, the template won't suffice. For such instances, you need to write your AutoActions using the Expert Mode template with the rules and some actions written in JSON.

Below are a variety of AutoActions written using JSON.

MapReduce
AA-Sample-image2017-10-20_22-43-6.png
Alert on MapReduce jobs using > 1 TB of memory.
{
  "scope": "multi_app",
  "type": "MAPREDUCE",
  "metric": "allocated_mb",
  "compare": ">",
  "value": 1073741824
}
Alert on MapReduce jobs using > 1000 vCores.
{
  "scope": "multi_app",
  "type": "MAPREDUCE",
  "metric": "allocated_vcores",
  "compare": ">",
  "value": 1000
}
Alert on MapReduce jobs running more than 1 hour.
{
 "scope": "multi_app",
 "type": "MAPREDUCE",
 "metric": "elapsed_time",
 "compare": ">",
 "value": 3600000
}
Alert on MapReduce jobs that may affect any production SLA jobs running on a cluster.

Check for MapReduce jobs not in the SLA queue, running between 12 am and 3 am, and using > 1 TB of memory.

Use the JSON rule specifying Map Reduce jobs using > 1 TB and set the rule conditions as shown.

AA_image2017-10-20_22-40-12.png
AA-Sample-image2017-10-20_22-59-5.png
Alert on ad hoc MapReduce jobs use a majority of cluster resources which may impact the cluster performance.

Check for MapReduce Jobs in the “root.adhocd” queue, running between 1 am and 5 am, and using > 1 TB of memory.

Use the JSON rule specifying Map Reduce jobs using > 1 TB and set the rule conditions as shown.

}
USER

User Alert for Rogue User - Any user consuming a major portion of cluster resources.

  • Check for any user where the allocated vCores aggregated over all their apps is > 1000.

    You can use the Rogue User template,

    AA-Sample-image2017-10-20_22-55-57.png

    or the JSON rule.

    {
  "scope": "multi_user",
  "metric": "allocated_vcores",
  "compare": ">",
  "value": 1000
}

  • Check for any user where the allocated memory aggregated over all their apps is > 1 TB.

    You can use the Rouge User template or the JSON rule.

    {
  "scope": "multi_user",
  "metric": "allocated_mb",
  "compare": ">",
  "value": 1073741824
}
Queue
Alert for rogue queue - any queue consuming a major portion of cluster resources.

  • Check for any queue where the allocated vCores aggregated overall its apps for any queue > 1000.

    {
  "scope": "multi_queue",
  "metric": "allocated_vcores",
  "compare": ">",
  "value": 1000
}

  • Check for any queue where the allocated memory aggregated overall its apps is > 1 TB.

    {
  "scope": "multi_queue",
  "metric": "allocated_mb",
  "compare": ">",
  "value": 1073741824
}
Applications

While apps in quarantine queue continue to run, the queue is preemptable and has a low resource allocation. If any other queue needs resources, it can preempt apps in the quarantine queue. Moving rogue apps to quarantine queue frees resources for other apps. Below we are alerting on vCores; to alert on memory just substitute memory for vCores in the following rules.

Alert for rogue app
If any app (not SLA bound) is consuming more than certain vCores at midnight, move it to a quarantine queue.

You can use the Rogue Application template to specify vCores.

AA-Sample-image2017-10-20_22-58-26.png

Or the Expert Mode template and set JSON rule for vCores as

{
  "scope": "multi_app",
  "metric": "allocated_vcores",
  "compare": ">",
  "value": 1000
}

Set Time rule condition as:

AA-Sample-image2017-10-20_22-59-5.png

Set Move app rule as:

AA-Sample-image2017-10-20_22-59-21.png
Any app needing greater than X amount of resources has to be approved, otherwise the app is moved to the quarantine queue.

You can use the Rogue Application template to specify vCores.

AA-Sample-image2017-10-20_22-59-40.png

Or use the Expert Mode template and set JSON rule as for vCores

{
  "scope": "multi_app",
  "metric": "allocated_vcores",
  "compare": ">",
  "value": [X]
}

Set Queue rule conditions.

AA-Sample-image2017-10-20_23-0-16.png

Set Move app queue action.

Regular Expressions (regex)

You can add regular expressions (regex) to AutoActions templates when you narrow the scope of User, Queue, Cluster, Workspace, Time, and Application Name by using Only or Except. Use the Transform box to specify the regex. You must first select the scope (User, Queue, Cluster, Workspace, Time, Application Name ) and then only specify the regular expressions.

In the following example, the Application name is used in the Only mode for SelectApps. The following regex is added in the Transform box, which is applied only for SelectApps.

regex/(.*)(GetReportGeneric|PreReport|final_vmin_v1_SAND_rkaranax_220406_1721_debug_3)(.*)/IntelMidasReports101/g

Other regex examples for AutoActions:

regex/^svc.*/serviceAccounts/g

regex/^svc. */serviceAccounts/g

regex/*condition-identification-processing-pipeline-wf*/cipp-wf/g

regex/^(xalxq)(.*)/serviceAccounts/g

regex/( .*)(_dc_l_logger_)(.*)/streamingJobs/g

regex/. {5 }/User5plus/g

Note

Keyword regex is mandatory. regex keyword is similar to substitute s in regular expressions.
