ArangoDB Server Metrics
arangod exports metrics which can be used to monitor the healthiness and performance of the system. Out of all exposed metrics the most relevant ones are highlighted below. In addition, the thresholds for alerts are described.
The list of exposed metrics is subject to change in every minor version. While they should stay backwards compatible for the most part, some metrics are coupled to specific internals that may be replaced by other mechanisms in the future.
Below monitoring recommendations are limited to those metrics that are considered future-proof. If you setup your monitoring to use the recommendations described here, you can safely upgrade to new versions.
Cluster Health
This group of metrics are used to measure how healthy the cluster processes are and if they can communicate properly to one another.
Heartbeats
Heartbeats are a core mechanism in ArangoDB Clusters to define the liveliness of Servers. Every server will send heartbeats to the agency, if too many heartbeats are skipped or cannot be delivered in time, the server is declared dead and a failover of the data will be triggered. By default we expect at least 1 heartbeat per second. If a server does not deliver 5 heartbeats in a row (5 seconds without a single heartbeat) it is considered dead.
Metric
arangodb_heartbeat_send_time_msec: The time a single heartbeat took to be delivered.arangodb_heartbeat_failures: Amount of heartbeats which this server failed to deliver.
Exposed by Coordinator, DB-Server
Threshold
- For
arangodb_heartbeat_send_time_msec:- Depending on your network latency, we typically expect this to be somewhere below 100ms.
- below 1000ms is still acceptable but not great.
- 1000ms - 3000ms is considered critical, but cluster should still operate, consider contacting our support.
- above 3000ms expect outages! If any of these fails to deliver, the server will be flagged as dead and we will trigger failover. With this timing the failovers will most likely stack up and cause more trouble.
- For
arangodb_heartbeat_failures:- Typically this should be 0.
- If you see any other value here this is typically a network hiccup.
- If this is constantly growing this means the server is somehow undergoing a network split.
Troubleshoot
Heartbeats are precious and on the fastest possible path internally. If they slow down or cannot be delivered this in almost all cases can be appointed to network issues. If you constantly have this on a high value please make sure the latency between your cluster machines and all agents is low, this will be a lower bound for the value we achieve here. If this is not the case, the network might be overloaded.
Agency Plan Sync on DB-Servers
In order to update the data definition on databases servers from the definition stored in the agency, DB-Servers have a repeated job called Agency Plan Sync. Timings for collection and database creations are strongly correlated to the overall runtime of this job.
Metric
arangodb_maintenance_agency_sync_runtime_msec: Histogram containing the runtimes of individual runs.arangodb_maintenance_agency_sync_accum_runtime_msec: The accumulated runtime of all runs.
Exposed by DB-Server
Threshold
- For
arangodb_maintenance_agency_sync_runtime_msec:- This should not exceed 1000ms.
Troubleshoot
If the Agency Plan Sync becomes the bottleneck of database and collection distribution you should consider reducing the amount of those.
Shard Distribution
Allows insight in the shard distribution in the cluster and the state of replication of the data.
Metric
arangodb_shards_out_of_sync: Number of shards not replicated with their required replication factor (for which this server is the leader)arangodb_shards_total_count: Number of shards located on this server (leader and follower shards)arangodb_shards_leader_count: Number of shards for which this server is the leader.arangodb_shards_not_replicated: Number of shards that are not replicated, i.e. this data is at risk as there is no other copy available.
Exposed by DB-Server
Threshold
- For
arangodb_shards_out_of_sync:- Eventually all shards should be in sync and this value equal to zero.
- It can increase when new collections are created or servers are rotated.
- For
arangodb_shards_total_countandarangodb_shards_leader_count:- This value should be roughly equal for all servers.
- For
arangodb_shards_not_replicated:- This value should be zero at all times. If not, you currently have a single point of failure and data is at risk. Please contact our support team.
- This can happen if you lose 1 DB-Server and have
replicationFactor2, if you lose 2 DB-Servers onreplicationFactor3 and so on. In this cases the system will try to heal itself, if enough healthy servers remain.
Troubleshoot
The distribution of shards should be roughly equal. If not please consider rebalancing shards.
Scheduler
The Scheduler is responsible for managing growing workloads and distributing tasks across the available threads. Whenever more work is available than the system can handle, it adjusts the number of threads. The scheduler maintains an internal queue for tasks ready for execution. A constantly growing queue is a clear sign for the system reaching its limits.
Metric
arangodb_scheduler_queue_length: Length of the internal task queue.arangodb_scheduler_awake_threads: Number of actively working threads.arangodb_scheduler_num_worker_threads: Total number of currently available threads.
Exposed by Coordinator, DB-Server, Agents
Threshold
- For
arangodb_scheduler_queue_length:- Typically this should be 0.
- Having an non-zero queue length is not a problem as long as it eventually becomes smaller again. This can happen for example during load spikes.
- Having a longer queue results in bigger latencies as the requests need to wait longer before they are executed.
- If the queue runs full you will eventually get a
queue fullerror.
- For
arangodb_scheduler_num_worker_threadsandarangodb_scheduler_awake_threads:- They should increase as load increases.
- If the queue length is non-zero for more than a minute you should see
arangodb_scheduler_awake_threads == arangodb_scheduler_num_worker_threads. If not, consider contacting our support.
Troubleshoot
Queuing requests will result in bigger latency. If your queue is constantly growing, you should consider scaling your system according to your needs. Remember to rebalance shards if you scale up DB-Servers.
Metric
arangodb_scheduler_queue_full_failures: Number of times a request/task could not be added to the scheduler queue because the queue was full. If this happens, the corresponding request will be responded to with an HTTP 503 (“Service Unavailable”) response.
Exposed by Coordinator, DB-Server, Agents
Threshold
- For
arangodb_scheduler_queue_full_failures:- This should be 0, as dropping requests is an extremely undesirable event.
Troubleshoot
If the number of queue full failures is greater than zero and even growing over time, it indicates that the server (or one of the server in a cluster) is overloaded and cannot keep up with the workload. There are many potential reasons for this, e.g. servers with too little capacity, spiky workloads, or even network connectivity issues. Whenever this problem happens, it needs further detailed analysis of what could be the root cause.
Supervision
The supervision is an integral part of the cluster and runs on the leading agent. It is responsible for handling MoveShard jobs and server failures. It is intended to run every second, thus its runime should be below one second.
Metric
arangodb_agency_supervision_runtime_msec: Time in ms of a single supervision run.arangodb_agency_supervision_runtime_wait_for_replication_msec: Time the supervision has to wait for its decisions to be committed.
Exposed by Agents
Threshold
- For
agency_supervision_runtime_msec:-
This value should stay below 1000ms. However, when a DB-Server is rotated there can be single runs that have much higher runtime. However, this should not be true in general.
This value will only increase for the leading agent.
-
Troubleshoot
If the supervision is not able to run approximately once per second, cluster resilience is affected. Please consider contacting our support.
Metrics API
Read the metrics
return the current instance metrics
GET /_admin/metrics
Returns the instance’s current metrics in Prometheus format. The returned document collects all instance metrics, which are measured at any given time and exposes them for collection by Prometheus.
The document contains different metrics and metrics groups dependent
on the role of the queried instance. All exported metrics are
published with the arangodb_ or rocksdb_ string to distinguish
them from other collected data.
The API then needs to be added to the Prometheus configuration file for collection.
Return codes
-
200: Metrics were returned successfully.
-
404: The metrics API may be disabled using
--server.export-metrics-api falsesetting in the server. In this case, the result of the call indicates the API to be not found.
