- healthy
- Is false when either the unbounded or plus request queues are full, true otherwise.
- host.memory.free
- Amount of free memory on the host.
- host.memory.quota
- The host memory quota. It reflects the node-quota setting.
- host.memory.total
- Total memory on the host.
- host.memory.value_quota
- This the total document memory quota on the node.
- load
- A calculation for how busy the server is.
- loadfactor
- The moving 15 minute average of the load calculation.
- node.allocated.values
- The total number of values allocated to contain documents or computations around documents. (This is only of relevance internally.)
- node.memory.usage
- The currently allocated document memory on the node.
- process.memory.usage
- Current process memory use.
- process.percore.cpupercent
- Average CPU usage per core.
- process.rss
- Process RSS (in bytes)
- process.service.usage
- The number of active servicers for the dominant workload - unbound queue servicers or plus queue servicers.
- request.queued.count
- Number of queued requests.
- request.quota.used.hwm
- High water mark for request quota use.
- servicers.paused.count
- Number of servicers temporarily paused due to memory pressure. (Applies to serverless environments only.)
- servicers.paused.total
- Number of times servicers have been temporarily paused. (Applies to serverless environments only.)
- temp.hwm
- High water mark for temp space use directly by Query. (Doesn't include use by the GSI and FTS clients.)
- temp.usage
- Current Query temp space use. (Doesn't include use by the GSI and FTS clients.)
