9 [command_options]
10
12 rabbitmq-diagnostics is a command line tool that provides commands used
13 for diagnostics, monitoring and health checks of RabbitMQ nodes. See the
14 RabbitMQ documentation guides:
15 https://rabbitmq.com/documentation.html
16 to learn more about RabbitMQ diagnostics, monitoring and health checks.
17
18 rabbitmq-diagnostics allows the operator to inspect node and cluster
19 state. A number of health checks are available to be used interactively
20 and by monitoring tools.
21
22
23 By default if it is not possible to connect to and authenticate with the
24 target node (for example if it is stopped), the operation will fail. To
25 learn more, see the RabbitMQ Monitoring guide:
26 https://rabbitmq.com/monitoring.html
27
29 -n node
30 Default node is "rabbit@target-hostname", where target-hostname
31 is the local host. On a host named "myserver.example.com", the
32 node name will usually be "rabbit@myserver" (unless
33 RABBITMQ_NODENAME has been overridden). The output of "hostname
34 -s" is usually the correct suffix to use after the "@" sign. See
35 rabbitmq-server(8) for details of configuring a RabbitMQ node.
36
37 -q, --quiet
38 Quiet output mode is selected. Informational messages are
39 reduced when quiet mode is in effect.
40
41 -s, --silent
42 Silent output mode is selected. Informational messages are
43 reduced and table headers are suppressed when silent mode is in
44 effect.
45
46 -t timeout, --timeout timeout
47 Operation timeout in seconds. Not all commands support timeouts.
48 Default is infinity.
49
50 -l, --longnames
51 Must be specified when the cluster is configured to use long
52 (FQDN) node names. To learn more, see the RabbitMQ Clustering
53 guide:
54 https://rabbitmq.com/clustering.html
55
56 --erlang-cookie cookie
57 Shared secret to use to authenticate to the target node. Prefer
58 using a local file or the RABBITMQ_ERLANG_COOKIE environment
59 variable instead of specifying this option on the command line.
60 To learn more, see the RabbitMQ CLI Tools guide:
61 https://rabbitmq.com/cli.html
62
64 Most commands provided by rabbitmq-diagnostics inspect node and cluster
65 state or perform health checks.
66
67 Commands that list topology entities (e.g. queues) use tab as column
68 delimiter. These commands and their arguments are delegated to rabbit‐
69 mqctl(8).
70
71 Some commands ( list_queues, list_exchanges, list_bindings and
72 list_consumers) accept an optional vhost parameter.
73
74 The list_queues, list_exchanges and list_bindings commands accept an
75 optional virtual host parameter for which to display results. The
76 default value is "/".
77
78 Help

146 Example:
147
148 rabbitmq-diagnostics certificates
149
150 check_alarms
151
152 Health check that fails (returns with a non-zero code) if there are
153 alarms in effect on any of the cluster nodes.
154
155 See RabbitMQ Resource Alarms guide:
156 https://rabbitmq.com/alarms.html

158
159 Example:
160 rabbitmq-diagnostics check_alarms
161
162 check_certificate_expiration [--unit time_unit] [--within seconds]
163
164 Checks the expiration date on the certificates for every listener
165 on target node that is configured to use TLS. Supported time units
166 are:
167
168 · days
169
170 · weeks
171

195 tener ports on the target node cannot accept a new TCP connection
196 opened by rabbitmq-diagnostics
197
198 The check only validates if a new TCP connection is accepted. It
199 does not perform messaging protocol handshake or authenticate.

207
208 check_port_listener port
209
210 Health check that fails (returns with a non-zero code) if the tar‐
211 get node is not listening on the specified port (there is no lis‐
212 tener that uses that port).

239 fail.

368 listeners
369
370 Lists listeners (bound sockets) on this node. Use this to inspect
371 what protocols and ports the node is listening on for client, CLI
372 tool and peer connections.
373
374 See RabbitMQ Networking guide:

397 Periodically samples stack traces of all Erlang processes ("light‐
398 weight threads") on the node. Reports the processes for which stack
399 trace samples are identical.
400
401 Identical samples may indicate that the process is not making any
402 progress but is not necessarily an indication of a problem.
403
404 Example:
405 rabbitmq-diagnostics maybe_stuck -q
406

411
412 · bytes
413
414 · megabytes
415
416 · gigabytes
417
418 · terabytes
419
420 See RabbitMQ Memory Use guide:

426 rabbitmq-diagnostics memory_breakdown --unit gigabytes
427

431
432 Example:
433 rabbitmq-diagnostics observer --interval 10
434
435 ping
436
437 Most basic health check. Succeeds if target node (runtime) is run‐
438 ning and rabbitmq-diagnostics can authenticate with it success‐
439 fully.

447 Performs sampling of runtime (kernel) threads' activity for
448 interval seconds and reports it.
449
450 For this command to work, Erlang/OTP on the target node must be
451 compiled with microstate accounting support and have the run‐
452 time_tools package available.
453
454 Example:
455 rabbitmq-diagnostics runtime_thread_stats --sample-interval
456 15

472
473 tls_versions
474
475 Lists all TLS versions supported by the runtime on the target node.
