CBC-SUBDOC(1) CBC-SUBDOC(1) NAME cbc-subdoc - Interactively Inspect Document Using Subdocument API SYNOPSIS cbc-subdoc [OPTIONS] DESCRIPTION cbc-subdoc runs an interactive shell with commands from subdocument API. OPTIONS Options may be read either from the command line, or from a configura- tion file (see cbcrc(4)): The following options control workload generation: -U, --spec=SPEC A string describing the cluster to connect to. The string is in a URI-like syntax, and may also contain other options. See the EXAMPLES section for information. Typically such a URI will look like couchbase://host1,host2,host3/bucket. The default for this option is couchbase://localhost/default -u, --username=USERNAME Specify the username for the bucket. Since Couchbase 5.x this is mandatory switch, and it must specify the name of the user ex- isiting on cluster (read more at "Security/Authorization" sec- tion of the server manual). For older servers this field should be either left empty or set to the name of the bucket itself. -P, --password=PASSWORD: -P -, --password=- Specify the password for the bucket. As for servers before 5.x this was only needed if the bucket is protected with a password. For cluster version after 5.x, the password is mandatory, and should match the selected account (read more at "Security/Autho- rization" section of the server manual). Specifying the - as the password indicates that the program should prompt for the password. You may also specify the pass- word on the commandline, directly, but is insecure as command line arguments are visible via commands such as ps. -T, --timings Dump command timings at the end of execution. This will display a histogram showing the latencies for the commands executed. -v, --verbose Specify more information to standard error about what the client is doing. You may specify this option multiple times for in- creased output detail. -D, --cparam=OPTION=VALUE Provide additional client options. Acceptable options can also be placed in the connection string, however this option is pro- vided as a convenience. This option may be specified multiple times, each time specifying a key=value pair (for example, -Dop- eration_timeout=10 -Dconfig_cache=/foo/bar/baz). See ADDITIONAL OPTIONS for more information -y, --compress Enable compressing of documents. When the library is compiled with compression support, this option will enable Snappy com- pression for outgoing data. Incoming compressed data handled au- tomatically regardless of this option. Note, that because the compression support have to be negotiated with the server, first packets might be sent uncompressed even when this switch was specified. This is because the library might queue data commands before socket connection has been established, and the library will negotiate compression feature. If it is known that all server support compression repeating the switch (like -yy) will force compression for all outgoing mutations, even scheduled be- fore establishing connection. --truststorepath=PATH The path to the server's SSL certificate. This is typically re- quired for SSL connectivity unless the certificate has already been added to the OpenSSL installation on the system (only ap- plicable with couchbases:// scheme) --certpath=PATH The path to the server's SSL certificate. This is typically re- quired for SSL connectivity unless the certificate has already been added to the OpenSSL installation on the system (only ap- plicable with couchbases:// scheme). This also should contain client certificate when certificate authentication used, and in this case other public certificates could be extracted into truststorepath chain. --keypath=PATH The path to the client SSL private key. This is typically re- quired for SSL client certificate authentication. The certifi- cate itself have to go first in chain specified by certpath (only applicable with couchbases:// scheme) --dump Dump verbose internal state after operations are done. ADDITIONAL OPTIONS The following options may be included in the connection string (via the -U option) as URI-style query params (e.g. couchbase://host/bucket?op- tion1=value1&option2=value2) or as individual key=value pairs passed to the -D switch (e.g. -Doption1=value1 -Doption2=value). The -D will in- ternally build the connection string, and is provided as a convenience for options to be easily passed on the command-line • operation_timeout=SECONDS: Specify the operation timeout in sec- onds. This is the time the client will wait for an operation to complete before timing it out. The default is 2.5 • config_cache=PATH: Enables the client to make use of a file based configuration cache rather than connecting for the bootstrap opera- tion. If the file does not exist, the client will first connect to the cluster and then cache the bootstrap information in the file. • truststorepath=PATH: The path to the server's SSL certificate. This is typically required for SSL connectivity unless the certificate has already been added to the OpenSSL installation on the system (only applicable with couchbases:// scheme) • certpath=PATH: The path to the server's SSL certificate. This is typically required for SSL connectivity unless the certificate has already been added to the OpenSSL installation on the system (only applicable with couchbases:// scheme). This also should contain client certificate when certificate authentication used, and in this case other public certificates could be extracted into trust- storepath chain. • keypath=PATH: The path to the client SSL private key. This is typi- cally required for SSL client certificate authentication. The cer- tificate itself have to go first in chain specified by certpath (only applicable with couchbases:// scheme) • ipv6=allow: Enable IPv6. • ssl=no_verify: Temporarily disable certificate verification for SSL (only applicable with couchbases:// scheme). This should only be used for quickly debugging SSL functionality. • sasl_mech_force=MECHANISM: Force a specific SASL mechanism to be used when performing the initial connection. This should only need to be modified for debugging purposes. The currently supported mechanisms are PLAIN and CRAM-MD5 • bootstrap_on=<both,http,cccp>: Specify the bootstrap protocol the client should use when attempting to connect to the cluster. Op- tions are: cccp: Bootstrap using the Memcached protocol (supported on clusters 2.5 and greater); http: Bootstrap using the HTTP REST protocol (supported on any cluster version); and both: First at- tempt bootstrap over the Memcached protocol, and use the HTTP pro- tocol if Memcached bootstrap fails. The default is both • enable_tracing=true/false: Activate/deactivate end-to-end tracing. • tracing_orphaned_queue_flush_interval=SECONDS: Flush interval for orphaned spans queue in default tracer. This is the time the tracer will wait between repeated attempts to flush most recent orphaned spans. Default value is 10 seconds. • tracing_orphaned_queue_size=NUMBER: Size of orphaned spans queue in default tracer. Queues in default tracer has fixed size, and it will remove information about older spans, when the limit will be reached before flushing time. Default value is 128. • tracing_threshold_queue_flush_interval=SECONDS: Flush interval for spans with total time over threshold in default tracer. This is the time the tracer will wait between repeated attempts to flush threshold queue. Default value is 10 seconds. • tracing_threshold_queue_size=NUMBER: Size of threshold queue in de- fault tracer. Queues in default tracer has fixed size, and it will remove information about older spans, when the limit will be reached before flushing time. Default value is 128. • tracing_threshold_kv=SECONDS: Minimum time for the tracing span of KV service to be considered by threshold tracer. Default value is 0.5 seconds. • tracing_threshold_query=SECONDS: Minimum time for the tracing span of QUERY service to be considered by threshold tracer. Default value is 1 second. • tracing_threshold_view=SECONDS: Minimum time for the tracing span of VIEW service to be considered by threshold tracer. Default value is 1 second. • tracing_threshold_search=SECONDS: Minimum time for the tracing span of SEARCH service to be considered by threshold tracer. Default value is 1 second. • tracing_threshold_analytics=SECONDS: Minimum time for the tracing span of ANALYTICS service to be considered by threshold tracer. De- fault value is 1 second.
