This will skip prompts for user input, with the +exception of a prompt for the SSH password. +.TP +\fB\-\-all\-logs\fR +Sosreport option. Collects all logs regardless of size. + +Default: no +.TP +\fB\-c\fR CLUSTER_OPTIONS +Specify options used by cluster profiles. The format is 'profile.option_name=value'. + +For example, for the ovirt plugin if you wanted to restrict node enumeration to +a specific cluster you would use \fB'-c ovirt.cluster=example_cluster'\fR. + +Available cluster options can be listed by running \fB'sos collect -l'\fR. +.TP +\fB\-\-chroot\fR CHROOT +Sosreport option. Set the chroot mode. When \fB\-\-sysroot\fR is used commands default +to executing with SYSROOT as the root directory. This can be overridden by setting +\fB\-\-chroot\fR to "always" (always chroot) or "never" (always run in the host +namespace). +.TP +\fB\-\-case\-id\fR CASE_ID +Sosreport option. Specifies a case number identifier. +.TP +\fB\-\-cluster\-type\fR CLUSTER_TYPE +When run by itself, sos collect will attempt to identify the type of cluster at play. +This is done by checking package or configuration information against the localhost, or +the master node if \fB"--master"\fR is supplied. + +Setting \fB--cluster-type\fR skips this step and forcibly sets a particular profile. + +Using a value of \fBnone\fR or \fBjbon\fR (just a bunch of nodes) will effectively +disable all cluster-specific checks, and cause sos collect to only use the nodes +specified by the \fB--nodes\fR option. Note that in this scenario, regex string(s) +for node names will be ignored. + +Example: \fBsos collect --cluster-type=kubernetes\fR will force the kubernetes profile +to be run, and thus set sosreport options and attempt to determine a list of nodes using +that profile. +.TP +\fB\-e\fR ENABLE_PLUGINS, \fB\-\-enable\-plugins\fR ENABLE_PLUGINS +Sosreport option. Use this to enable a plugin that would otherwise not be run. + +This option supports providing a comma-delimited list of plugins. +.TP +.B \--encrypt-key KEY +Encrypts the resulting archive that sos collect produces using GPG. KEY must be +an existing key in the user's keyring as GPG does not allow for keyfiles. +KEY can be any value accepted by gpg's 'recipient' option. + +Note that the user running sos collect must match the user owning the keyring +from which keys will be obtained. In particular this means that if sudo is +used to run sos collect, the keyring must also be set up using sudo +(or direct shell access to the account). + +Users should be aware that encrypting the final archive will result in sos +using double the amount of temporary disk space - the encrypted archive must be +written as a separate, rather than replacement, file within the temp directory +that sos writes the archive to. However, since the encrypted archive will be +the same size as the original archive, there is no additional space consumption +once the temporary directory is removed at the end of execution. + +This means that only the encrypted archive is present on disk after sos +finishes running. + +If encryption fails for any reason, the original unencrypted archive is +preserved instead. + +IMPORTANT: As of this version of sos collect, only the final archive on the +local machine running sos collect will be encrypted. The individual sos reports +that are collected on the nodes will be collected unencrypted. +.TP +.B \--encrypt-pass PASS +The same as \--encrypt-key, but use the provided PASS for symmetric encryption +rather than key-pair encryption. +.TP + +\fB\-\-group\fR GROUP +Specify an existing host group definition to use. + +Host groups are pre-defined settings for the cluster-type, master, and nodes options +saved in JSON-formatted files under /var/lib/sos collect/<GROUP>. + +If cluster_type and/or master are set in the group, sos collect behaves as if +these values were specified on the command-line. + +If nodes is defined, sos collect \fBextends\fR the \fB\-\-nodes\fR option, if set, +with the nodes or regexes listed in the group. + +Note that sos collect will only write group definitions to /var/lib/sos collect/ +however the GROUP value may be a filename for any group definitions that exist outside +of the default location. If you are manually writing these files, use the value \fBnull\fR +when a python NoneType is expected. Caveat: use \fBstring\fR 'none' if setting cluster_type +to none. +.TP +\fB\-\-save\-group\fR GROUP +Save the results of this run of sos collect to a host group definition. + +sos-colllector will write a JSON-formatted file with name GROUP to /var/lib/sos collect/ +with the settings for cluster-type, master, and the node list as discovered by cluster enumeration. +Note that this means regexes are not directly saved to host groups, but the results of matching against +those regexes are. +.TP +\fB\-\-insecure-sudo\fR +Use this option when connecting as a non-root user that has passwordless sudo +configured. + +If this option is omitted and a bogus sudo password is supplied, collection of +sosreports may exhibit unexpected behavior and/or fail entirely. +.TP +\fB\-k\fR PLUGIN_OPTION, \fB\-\-plugin\-option\fR PLUGIN_OPTION +Sosreport option. Set a plugin option to a particular value. This takes the form of +plugin_name.option_name=value. + +Example: To enable the kubernetes "all" option in sosreport use \fB-k kubernetes.all=on\fR. +.TP +\fB\-\-label\fR LABEL +Specify a label to be added to the archive names. This label will be applied to +both the sos collect archive and the sosreport archives. + +If a cluster sets a default label, the user-provided label will be appended to +that cluster default. +.TP +\fB\-n\fR SKIP_PLUGINS, \fB\-\-skip\-plugins\fR SKIP_PLUGINS +Sosreport option. Disable (skip) a particular plugin that would otherwise run. +This is useful if a particular plugin is prone to hanging for one reason or another. + +This option supports providing a comma-delimited list of plugins. +.TP +\fB\-\-nodes\fR NODES +Provide a comma-delimited list of nodes to collect sosreports from, or a regex string to +be used to compare discovered node names against. If using a regex, only nodes matching the regex +will be used - i.e. it can be used as a whitelist but not a blacklist. + +This option can be handed multiple regex strings separated by commas. Additionally, both whole node +names/addresses and regex strings may be provided at the same time. +.TP +\fB\-\-no\-pkg\-check\fR +Do not perform package checks. Most cluster profiles check against installed packages to determine +if the cluster profile should be applied or not. + +Use this with \fB\-\-cluster-type\fR if there are rpm or apt issues on the master/local node. +.TP +\fB\-\-no\-local\fR +Do not collect a sosreport from the local system. + +If \fB--master\fR is not supplied, it is assumed that the host running sosreport is part of +the cluster that is to be collected. Use this option to skip collection of a local sosreport. + +This option is NOT needed if \fB--master\fR is provided. +.TP +\fB\-\-master\fR MASTER +Specify a master node for the cluster. + +If provided, then sos collect will check the master node, not localhost, for determining +the type of cluster in use. +.TP +\fB\-o\fR ONLY_PLUGINS, \fB\-\-only\-plugins\fR ONLY_PLUGINS +Sosreport option. Run ONLY the plugins listed. + +Note that a cluster profile will NOT override this option. This may cause the sosreports +generated to not contain the relevant output for a given type of cluster. + +This option supports providing a comma-delimited list of plugins. +.TP +\fB\-\-password\fR +Specifying this option will cause sos collect to prompt the user for an SSH password +that will be used to connect to all nodes. + +If you have differing passwords for the same user across cluster nodes, you should +ideally deploy SSH keys, but the \-\-password\-per\-node option is also available. +.TP +\fB\-\-password\-per\-node\fR +When using this option, sos collect will prompt the user for the SSH password for +each node that will have an sosreport collected from it individually before attempting +to connect to the nodes. +.TP +\fB\-\-preset\fR PRESET +Specify a sos preset to use, note that this requires sos-3.6 or later to be installed +on the node. The given preset must also exist on the remote node - local presets +are not used. + +If \fB\-\-preset\fR is specified and a given node either does not have that preset +defined, or has a version of sos prior to 3.6, this option is ignored for that node. +.TP +\fB\-p\fR SSH_PORT, \fB\-\-ssh\-port\fR SSH_PORT +Specify SSH port for all nodes. Use this if SSH runs on any port other than 22. +.TP +\fB\-\-ssh\-user\fR SSH_USER +Specify an SSH user for sos collect to connect to nodes with. Default is root. + +sos collect will prompt for a sudo password for non-root users. +.TP +\fB\-s\fR SYSROOT, \fB\-\-sysroot\fR SYSROOT +Sosreport option. Specify an alternate root file system path. +.TP +\fB\-\-sos-cmd\fR SOS_CMD +Define all options that sosreport should be run with on the nodes. This will +override any other commandline options as well as any options specified by a +cluster profile. + +The sosreport command will execute as 'sosreport --batch SOS_CMD'. The BATCH +option cannot be removed from the sosreport command as it is required to run +sosreport non-interactively for sos collect to function. +.TP +\fB\-t\fR THREADS \fB\-\-threads\fR THREADS +Specify the number of threads to use for concurrent collection of sosreports. + +If the number of nodes enumerated exceeds the number of threads, then sos collect +will start collecting from the first X number of nodes and then continue to iterate +through the remaining nodes as sosreport collection finishes. + +Defaults to 4. +.TP +\fB\-\-timeout\fR TIMEOUT +Timeout for sosreport generation on each node, in seconds. + +Note that sosreports are collected in parallel, so this can also be considered to be +approximately the same as a timeout for the entire collection process. + +Default is 180 seconds. +.TP +\fB\-\-tmp\-dir\fR TMP_DIR +Specify a temporary directory to save sos archives to. By default one will be created in +/tmp and then removed after sos collect has finished running. + +This is NOT the same as specifying a temporary directory for sosreport on the remote nodes. +.TP +\fB\-v\fR \fB\-\-verbose\fR +Print debug information to screen. +.TP +\fB\-\-verfiy\fR +Sosreport option. Passes the "--verify" option to sosreport on the nodes which +causes sosreport to validate plugin-specific data during collection. + +Note that this option may considerably extend the time it takes sosreport to run on +the nodes. Consider increasing \fB\-\-timeout\fR when using this option. +.TP +\fB\-z\fR COMPRESSION, \fB\-\-compression-type\fR COMPRESSION +Sosreport option. Override the default compression type. + +.SH SEE ALSO +.BR sos (1) +.BR sos-report (1) + +.SH MAINTAINER + Jake Hunsaker <jhunsake@redhat.com> |
