Below are several of our common issues we see in Support and what you can proactively provide to help Redpanda Support more efficiently review your ticket. Self Hosted customers should always submit a debug bundle in addition to anything else.
Console Issues
- Capture the problem with a screenshot or a quick video
- Also capture the problem in HAR format. See this KB for more information.
- Send the Console log. (Self Hosted Customers Only)
Client Issues
- Tell us the client implementation along with its version
- Send the full client log that shows the problem
Broker Crashing Issues (Self Hosted Customers Only)
- Send the log that covers the time the process crashed.
- Tell us about the redpanda version and the CPU architecture type.
Tiered Storage Issues
- Collect "rpk debug bundle --partition <comma separated problematic partitions list>" from all nodes
- Provide 2 or 3 partitions as a sample
Latency Issues
- Tell us how the latency is measured.
- Tell us how it looked before and how it looks now.
- Tell us what is the expected latency.
- Tell us about the deployment details; cloud vendors, machine type, disk details. (Self Hosted Customers Only)
- Tell us about any environment details, client and cluster, that have changed around the time of the change in latency.
Consumer Lag issues
- Tell us the consumer client implementation along with its version.
- Tell us the group & topic names in question.
- Tell us when the lag started to happen.
- Share some metrics charts that denote lags.
- Did the lag abruptly increase or gradually?
- If the lag abruptly increased, run "rpk debug bundle --logs-since xxx --logs-until yyy" and ensure it captures the time the lag happened. Also send all content under /var/lib/redpanda/data/kafka/__consumer_offsets from all nodes. (Self Hosted Customers Only)
- If the lag gradually increased, send the client logs along with "rpk debug bundle --logs-since xxx" (Self Hosted Customers Only)
Cluster Health Issue (Self Hosted Customers Only)

- Collect "rpk debug bundle --partition <comma separated some problematic partition list>" from all nodes.
Under-replicated partitions
