About this RabbitMQ load test
Load tests RabbitMQ: the AMQP protocol handshake, the alarms health check, the management API overview, queue list and connection list, and a management call without credentials that must be refused. It shows how connections and the management API scale.
It holds 18 ready-made jobs: 6 single scenarios and an enterprise test plan of 12 stages to run in order, 8 of them with pass/fail targets (SLOs). Each job is a plain request pattern you can change before running.
Scenarios include AMQP protocol handshake, health check: alarms, overview, queue list and connection list.
How to load test RabbitMQ
Open the template in BLASTA.
Set host and mgmt to point at your own RabbitMQ system, ideally a staging copy.
Pick a job and choose the rate and duration.
Start the run and watch requests per second, latency percentiles and errors live; the result is saved to your history.
What you set before running
host
Broker host name
amqpPort
AMQP port
mgmt
Management API URL, no trailing slash
basic
A credential, supplied as an environment variable and never typed into the form. base64(user:password) for the management API. Read from RABBITMQ_BASIC by the CLI.
Sends the AMQP 0-9-1 protocol header and checks that the broker answers with a Connection.Start frame. Every connection costs an Erlang process, so this is the connection-churn test.
Enterprise plan, step 1 of 10. One request a second for 30 seconds. Run this first, every time: it proves the address, credentials and headers are right and that the environment is up before any real load is applied. Gate: zero errors. Reference request: AMQP protocol handshake.
Step 2 of 10. About a fifth of normal traffic for 5 minutes: the uncontended latency of this request. Every later result is judged against it, so record p50 and p95. Gate: at most 0.5% errors and the default latency targets. Reference request: AMQP protocol handshake.
Step 3 of 10. Normal busy-hour traffic for 10 minutes. The rate is the reference job's rate: raise it to your measured production peak-hour rate. This is the run that proves (or breaks) your SLO. Gate: at most 1% errors, p95 and p99 inside the targets. Reference request: AMQP protocol handshake.
Step 4 of 10. Twice the average for 10 minutes: the busiest hour of the year plus headroom. Latency may rise, but must stay in SLO; if it does not, you have no headroom. Gate: at most 2% errors, latency targets doubled. Reference request: AMQP protocol handshake.
Step 5 of 10. Ramps to four times average over 10 minutes, then holds for 2. Finds where it degrades and HOW: gracefully (latency rises, errors stay low) or badly (errors, timeouts, crashes, restarts). Observation only, no gate. Reference request: AMQP protocol handshake.
Step 6 of 10. Reaches ten times average within 10 seconds and holds for 2 minutes: a campaign email, a news link, a failover. Checks autoscaling, queue limits and load shedding. Gate: at most 5% errors, because shedding load is acceptable and crashing is not. Reference request: AMQP protocol handshake.
Step 7 of 10. Run IMMEDIATELY after the spike, at average load for 5 minutes. Latency and errors must return to the baseline from step 2. If they do not, something is stuck: queues, connection pools, GC, an autoscaler cool-down. Gate: same as average load. Reference request: AMQP protocol handshake.
Step 8 of 10. One hour of steady load. Finds leaks and slow decay in memory, connections, file descriptors, disk, log volume and cache churn. Watch the resource graphs: any line that climbs and never flattens is a finding. Gate: at most 0.5% errors. Reference request: AMQP protocol handshake.
Step 9 of 10. Ramps to twenty times average over 20 minutes. Stop it when errors pass about 5%: the rate at that moment is your ceiling, and ceiling divided by peak is your capacity margin. Use a production-like environment, never production. Reference request: AMQP protocol handshake.
Step 10 of 10. Average load for 15 minutes. About 5 minutes in, cause the event you are testing: kill a pod or node, fail over the database, roll out a new version, drain a zone. Errors in the window are your real availability loss. Gate: at most 1% errors overall; read the time series for how long the dip lasted. Reference request: AMQP protocol handshake.
Ramps new connections per second to ten times normal: a fleet reconnecting after an outage, a deploy that restarts every pod, a network blip. Shows accept-queue, file descriptor and handshake limits. Reference request: AMQP protocol handshake.
Every producer and consumer reconnects after a broker restart. Ramps to ten times normal. Reference request: AMQP protocol handshake.
Frequently asked questions
What does the RabbitMQ load test cover?
The RabbitMQ template has 18 jobs: 6 single scenarios and an enterprise test plan of 12 stages (smoke, baseline, load, stress, spike, soak, breakpoint and failover window). Scenarios include AMQP protocol handshake, health check: alarms, overview and queue list. 8 of them have pass/fail targets (SLOs), so a run can be judged against limits you set.
How do I load test RabbitMQ with BLASTA?
Open the template in BLASTA and set host and mgmt, then pick a job and start it. Results stream live: requests per second, latency percentiles and errors, and the run is kept in your history. To run from the command line, use blasta preset new rabbitmq with your address.
Is it safe to run the RabbitMQ load test against production?
All 18 jobs in this template are read-only: they request pages or data and do not change anything. Even so, a load test can slow a live system down, so start with a low rate and prefer a staging copy. Only test systems you own or have permission to test.
Set up a target above and press Start test. Charts and numbers appear here as the test runs.
