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 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 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 -q, --quiet
38 Quiet output mode is selected. Informational messages are
39 reduced when quiet mode is in effect.
40 -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 -t timeout, --timeout timeout
47 Operation timeout in seconds. Not all commands support timeouts.
48 Default is infinity.
49 -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 --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 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 Some commands ( list_queues, list_exchanges, list_bindings and
72 list_consumers) accept an optional vhost parameter.
73 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 Help
79 help [-l] [command_name]
80 Prints usage for all available commands.
82 -l, --list-commands
84 List command usages only, without parameter explanation.
85 command_name

137 Example:
139 rabbitmq-diagnostics alarms
140 certificates
142 Displays the node certificates for every listener on target node
144 that is configured to use TLS.
145 Example:
147 rabbitmq-diagnostics certificates
149 check_alarms
151 Health check that fails (returns with a non-zero code) if there are
153 alarms in effect on any of the cluster nodes.
154 See RabbitMQ Resource Alarms guide:
156 https://rabbitmq.com/alarms.html
157 to learn more.
158 Example:
160 rabbitmq-diagnostics check_alarms
161 check_certificate_expiration [--unit time_unit] [--within seconds]
163 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 · days
169 · weeks
171 · months
173 · years
175 Example:
177 rabbitmq-diagnostics check_certificate_expiration --unit
178 weeks --within 6
179 check_local_alarms
181 Health check that fails (returns with a non-zero code) if there are
183 alarms in effect on the target node.

187 to learn more.
188 Example:
190 rabbitmq-diagnostics check_local_alarms
191 check_port_connectivity
193 Health check that fails (returns with a non-zero code) if any lis‐
195 tener ports on the target node cannot accept a new TCP connection
196 opened by rabbitmq-diagnostics
197 The check only validates if a new TCP connection is accepted. It
199 does not perform messaging protocol handshake or authenticate.
200 See RabbitMQ Networking guide:
202 https://rabbitmq.com/networking.html
203 to learn more.
204 Example:
206 rabbitmq-diagnostics check_port_connectivity

211 get node is not listening on the specified port (there is no lis‐
212 tener that uses that port).
213 See RabbitMQ Networking guide:
215 https://rabbitmq.com/networking.html
216 to learn more.
217 Example:
219 rabbitmq-diagnostics check_port_listener 5672

222 Health check that fails (returns with a non-zero code) if the tar‐
224 get node does not have a listener for the specified protocol.
225 See RabbitMQ Networking guide:
227 https://rabbitmq.com/networking.html
228 to learn more.
229 Example:
231 rabbitmq-diagnostics check_protocol_listener mqtt
232 check_running
234 Health check that fails (returns with a non-zero code) if the Rab‐
236 bitMQ application is not running on the target node.
237 If rabbitmqctl(8) was used to stop the application, this check will
239 fail.
240 Example:
242 rabbitmq-diagnostics check_running
243 check_virtual_hosts
245 Health check that checks if all vhosts are running in the target
247 node

394 maybe_stuck
396 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 Identical samples may indicate that the process is not making any
402 progress but is not necessarily an indication of a problem.
403 Example:
405 rabbitmq-diagnostics maybe_stuck -q
406 memory_breakdown [--unit memory_unit]
408 Displays node's memory usage by category. Supported memory units
410 are:

429 Starts a CLI observer interface on the target node
431 Example:
433 rabbitmq-diagnostics observer --interval 10
434 ping
436 Most basic health check. Succeeds if target node (runtime) is run‐
438 ning and rabbitmq-diagnostics can authenticate with it success‐
439 fully.
440 report
442 See report in rabbitmqctl(8)
444 runtime_thread_stats [--sample-interval interval]
446 Performs sampling of runtime (kernel) threads' activity for
448 interval seconds and reports it.
449 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 Example:
455 rabbitmq-diagnostics runtime_thread_stats --sample-interval
456 15
457 schema_info [--no_table_headers] [column ...] [--timeout milliseconds]
459 See schema_info in rabbitmqctl(8)

467 rabbitmq-diagnostics server_version -q
468 status
470 See status in rabbitmqctl(8)
472 tls_versions
474 Lists all TLS versions supported by the runtime on the target node.
476 Note that RabbitMQ can be configured to only accept a subset of
477 those versions, for example, SSLv3 is disabled by default.
