The RudderStack dashboard is powered by Grafana. It gives you detailed insights into your RudderStack server's performance. You get a real-time view of the events sent and received by RudderStack, along with various other metrics such as RudderStack's performance under load, errors encountered while processing events, statistics about event delivery, etc.
All the performance metrics are stored in InfluxDB, where Grafana queries them and gives you their visual overview.
This guide is aimed at explaining these performance metrics and the various dashboard panels in detail.
The following are some of the commonly used terms that you are likely to encounter in this guide:
Refers to the data warehouses like Amazon Redshift, Google BigQuery, Snowflake, ClickHouse, and PostgreSQL - which are currently supported by RudderStack.
Refers to the object storage destinations like Amazon S3, Google Cloud Storage, Azure Blob Storage, MinIO, and DigitalOcean Spaces - which are currently supported by RudderStack.
All the connected destinations other than the two mentioned above are referred to as router destinations.
Refers to RudderStack's internal service which allows you to transform your event payload into a destination-specific payload.
Refers to RudderStack's internal service which is responsible for ingesting the incoming events.
Refers to RudderStack's internal service which is responsible for processing new events, applying user transformations, and destination transformations.
The RudderStack dashboard is powered by Grafana, and gives you a complete picture of the total number of requests, as well as the events received and delivered via RudderStack.
Corresponds to the number of HTTP requests RudderStack has received in the selected time period.
This section refers to the number of events RudderStack has received in the selected time period. The RudderStack API allows multiple events to be batched inside a single HTTP request.
Refers to the number of events RudderStack has delivered across all destinations in a selected time period. If you have set up a warehouse destination in RudderStack, every event will be delivered into two different tables in warehouse and counted as two delivered events.
This section highlights the number of requests HTTP requests RudderStack has received across all sources in the selected time period. The details of an individual source can be found in Gateway Detailed section of the dashboard.
RudderStack has a reverse proxy in front of the RudderStack nodes. This panel lists all the HTTP responses codes. You can find the
4xx status if the requests are invalid, and
5xx status if the service is down or has encountered an internal error.
In this section, the events are stored to the gateway (PostgreSQL) and acknowledged. The time to acknowledge HTTP requests is listed with 99 percentile, 95 percentile, and mean times.
The RudderStack Processor module picks events from gateway for further processing. If
Input Requests >
Output Requests then the inflow is higher than what the processor can handle.
This section corresponds to the number of events delivered to the object storage destinations like Amazon S3, Google Cloud Storage, Azure Blob storage, MinIO, Digital Ocean Spaces, etc.
Indicates the number of events delivered to the data warehouse destinations like Amazon Redshift, Google BigQuery, Snowflake, ClickHouse, PostgreSQL, etc.
Indicates the number of events delivered to all the other destinations except the ones highlighted in the above two sections.
Corresponds to the average time taken for delivering the events to the object storage destinations. RudderStack batches events every 30 seconds (default value), so RudderStack takes at least this much time to batch the events and deliver them.
Highlights the longest sync delay for delivering the events to the warehouse destination. RudderStack batches events every 30 minutes (default value) before uploading to the data warehouse, so the delivery takes at least this much batching period.
This section reports the lag for the oldest event in a batch. For example, if the batching period is 30 minutes and the reported lag time is 50 minutes, then the average lag time would be 50 - (30/2) = 35 min
Corresponds to the average time taken to deliver the events to all other destinations.
This includes the list of all active destinations within the selected time window. The destination includes first 15 characters of the destination name and last 6 characters of RudderStack's internal destination ID.
This dashboard gives you the big picture of how the input events are multiplexed into the destination specific events.
This corresponds to the number of events generated by the processor per destination.
Indicates the time taken to generate the destination events. Note that these events are not yet sent to the destinations at this stage.
This dashboard indicates the number of errors incurred during the transformations. Some possible reasons include missing mandatory fields for a specific destination, invalid event types, erroneously high number of properties in the event for warehouse destinations, etc.
The router picks the transformed events that are ready to be sent to the destinations, and then forwards them to the destinations. If a destination is down for sometime, it retries up to a configured time window (default value being 3 hours). If IN > OUT (refer to the second graph in the image above), then there would be a delay in delivering the events. Some possible reasons include a sudden surge of events, or that the destination is slow in accepting new event requests.
This indicates all the destination HTTP responses grouped by the status code.
Corresponds to the metrics on any failures and retries before the event is delivered. If the event keeps failing event after a configured window, then it is marked aborted. The aborted events are also shown in this panel.
The warehouse uploads are run as scheduled in the configuration. If there is no schedule defined, uploads are run every 30 minutes and the batched data is loaded into the data warehouse.
The upload status of every batch is shown in the dashboard panel. If an upload keeps failing, it will be marked as aborted after 3 hours. Some possible failure reasons could be insufficient permissions to create and write to tables, reaching column limit on a specific table, warehouse brought down for maintenance, etc.
This graph corresponds to the number of events delivered to the warehouse destinations plotted against the time when the upload was completed.
Corresponds to the number of new rows created in the
grouped by table during warehouse uploads. In the example above, if there are different event names (eg.
user_signed_up ) they all are grouped under
others in the metrics.
This panel corresponds to the longest sync delay for delivering events to your warehouse destination. RudderStack batches events every 30 minutes (default value) before uploading to your data warehouse, so the delivery takes at least that much batching time. This panel reports the lag for the oldest event in a batch. For example, if the batching period is 30 min and the reported lag time is 50 min, then the average lag time would be 50 - (30/2) = 35 min.
This is the size of internal queue that RudderStack maintains for routing the events. There are 3 such queues named gateway (
gw), router (
rt) and batch router (
RudderStack processes events from these queues. If the size of the queue keeps increasing, it implies that the event outflow is less than inflow.
