Comes from [OperatingSystemMXBean#getSystemLoadAverage()](http://docs.oracle.com/javase/7/docs/api/java/lang/management/OperatingSystemMXBean.html?is-external=true#getSystemLoadAverage\(\)). -#### Alerting A high sustained value suggests that the scheduler machine may be over-utilized. -#### Triage Use standard unix tools like `top` and `ps` to track down the offending process(es). -#### `process_cpu_cores_utilized` +### `process_cpu_cores_utilized` Type: double gauge -#### Description The current number of CPU cores in use by the JVM process. This should not exceed the number of logical CPU cores on the machine. Derived from [OperatingSystemMXBean#getProcessCpuTime()](http://docs.oracle.com/javase/7/docs/jre/api/management/extension/com/sun/management/OperatingSystemMXBean.html) -#### Alerting A high sustained value indicates that the scheduler is overworked. Due to current internal design limitations, if this value is sustained at `1`, there is a good chance the scheduler is under water. -#### Triage There are two main inputs that tend to drive this figure: task scheduling attempts and status updates from Mesos. You may see activity in the scheduler logs to give an indication of where time is being spent. Beyond that, it really takes good familiarity with the code to effectively triage this. We suggest engaging with an Aurora developer. -#### `task_store_LOST` +### `task_store_LOST` Type: integer gauge -#### Description The number of tasks stored in the scheduler that are in the `LOST` state, and have been rescheduled. -#### Alerting If this value is increasing at a high rate, it is a sign of trouble. -#### Triage There are many sources of `LOST` tasks in Mesos: the scheduler, master, slave, and executor can all trigger this. The first step is to look in the scheduler logs for `LOST` to identify where the state changes are originating. -#### `scheduler_resource_offers` +### `scheduler_resource_offers` Type: integer counter -#### Description The number of resource offers that the scheduler has received. -#### Alerting For a healthy scheduler, this value must be increasing over time. -##### Triage Assuming the scheduler is up and otherwise healthy, you will want to check if the master thinks it is sending offers. You should also look at the master's web interface to see if it has a large number of outstanding offers that it is waiting to be returned. -#### `framework_registered` +### `framework_registered` Type: binary integer counter -#### Description Will be `1` for the leading scheduler that is registered with the Mesos master, `0` for passive schedulers, -#### Alerting A sustained period without a `1` (or where `sum() != 1`) warrants investigation. -#### Triage If there is no leading scheduler, look in the scheduler and master logs for why. If there are multiple schedulers claiming leadership, this suggests a split brain and warrants filing a critical bug. -#### `rate(scheduler_log_native_append_nanos_total)/rate(scheduler_log_native_append_events)` +### `rate(scheduler_log_native_append_nanos_total)/rate(scheduler_log_native_append_events)` Type: rate ratio of integer counters -#### Description This composes two counters to compute a windowed figure for the latency of replicated log writes. -#### Alerting A hike in this value suggests disk bandwidth contention. -#### Triage Look in scheduler logs for any reported oddness with saving to the replicated log. Also use standard tools like `vmstat` and `iotop` to identify whether the disk has become slow or over-utilized. We suggest using a dedicated disk for the replicated log to mitigate this. -#### `timed_out_tasks` +### `timed_out_tasks` Type: integer counter -#### Description Tracks the number of times the scheduler has given up while waiting (for `-transient_task_state_timeout`) to hear back about a task that is in a transient state (e.g. `ASSIGNED`, `KILLING`), and has moved to `LOST` before rescheduling. -#### Alerting This value is currently known to increase occasionally when the scheduler fails over ([AURORA-740](https://issues.apache.org/jira/browse/AURORA-740)). However, any large spike in this value warrants investigation. -#### Triage The scheduler will log when it times out a task. You should trace the task ID of the timed out task into the master, slave, and/or executors to determine where the message was dropped. -#### `http_500_responses_events` +### `http_500_responses_events` Type: integer counter -#### Description The total number of HTTP 500 status responses sent by the scheduler. Includes API and asset serving. -#### Alerting An increase warrants investigation. -#### Triage Look in scheduler logs to identify why the scheduler returned a 500, there should be a stack trace.
