condor_status

Display status of the HTCondor pool

Synopsis

condor_status [-debug] [help options] [query options] [display options] [custom options] [name …]

Description

condor_status is a versatile tool that may be used to monitor and query the HTCondor pool. The condor_status tool can be used to query resource information, submitter information, checkpoint server information, and daemon master information. The specific query sent and the resulting information display is controlled by the query options supplied. Queries and display formats can also be customized.

The options that may be supplied to condor_status belong to five groups:

• Help options provide information about the condor_status tool.
• Query options control the content and presentation of status information.
• Display options control the display of the queried information.
• Custom options allow the user to customize query and display information.
• Host options specify specific machines to be queried

At any time, only one help option, one query option and one display option may be specified. Any number of custom options and host options may be specified.

Options

-debug

Causes debugging information to be sent to stderr, based on the value of the configuration variable TOOL_DEBUG.

-help

(Help option) Display usage information.

-diagnose

(Help option) Print out ClassAd query without performing the query.

-absent

(Query option) Query for and display only absent resources.

-ads filename

(Query option) Read the set of ClassAds in the file specified by filename, instead of querying the condor_collector.

-annex name

(Query option) Query for and display only resources in the named annex.

-any

(Query option) Query all ClassAds and display their type, target type, and name.

-avail

(Query option) Query condor_startd ClassAds and identify resources which are available.

-ckptsrvr

(Query option) Query condor_ckpt_server ClassAds and display checkpoint server attributes.

-claimed

(Query option) Query condor_startd ClassAds and print information about claimed resources.

-cod

(Query option) Display only machine ClassAds that have COD claims. Information displayed includes the claim ID, the owner of the claim, and the state of the COD claim.

-collector

(Query option) Query condor_collector ClassAds and display attributes.

-defrag

(Query option) Query condor_defrag ClassAds.

-direct hostname

(Query option) Go directly to the given host name to get the ClassAds to display. By default, returns the condor_startd ClassAd. If -schedd is also given, return the condor_schedd ClassAd on that host.

-java

(Query option) Display only Java-capable resources.

-license

(Query option) Display license attributes.

-master

(Query option) Query condor_master ClassAds and display daemon master attributes.

-negotiator

(Query option) Query condor_negotiator ClassAds and display attributes.

-pool centralmanagerhostname[:portnumber]

(Query option) Query the specified central manager using an optional port number. condor_status queries the machine specified by the configuration variable COLLECTOR_HOST by default.

-run

(Query option) Display information about machines currently running jobs.

-schedd

(Query option) Query condor_schedd ClassAds and display attributes.

-server

(Query option) Query condor_startd ClassAds and display resource attributes.

-startd

(Query option) Query condor_startd ClassAds.

-state

(Query option) Query condor_startd ClassAds and display resource state information.

-statistics WhichStatistics

(Query option) Can only be used if the -direct option has been specified. Identifies which Statistics attributes to include in the ClassAd. WhichStatistics is specified using the same syntax as defined for STATISTICS_TO_PUBLISH. A definition is in the HTCondor Administrator’s manual section on configuration (section 3.5.1).

-storage

(Query option) Display attributes of machines with network storage resources.

-submitters

(Query option) Query ClassAds sent by submitters and display important submitter attributes.

-subsystem type

(Query option) If type is one of collector, negotiator, master, schedd, or startd, then behavior is the same as the query option without the -subsystem option. For example, -subsystem collector is the same as -collector. A value of type of CkptServer, Machine, DaemonMaster, or Scheduler targets that type of ClassAd.

-vm

(Query option) Query condor_startd ClassAds, and display only VM-enabled machines. Information displayed includes the machine name, the virtual machine software version, the state of machine, the virtual machine memory, and the type of networking.

-offline

(Query option) Query condor_startd ClassAds, and display, for each machine with at least one offline universe, which universes are offline for it.

-attributes Attr1[,Attr2 …]

(Display option) Explicitly list the attributes in a comma separated list which should be displayed when using the -xml, -json or -long options. Limiting the number of attributes increases the efficiency of the query.

-expert

(Display option) Display shortened error messages.

-long

(Display option) Display entire ClassAds. Implies that totals will not be displayed.

-limitnum

(Query option) At most num results should be displayed.

-sort expr

(Display option) Change the display order to be based on ascending values of an evaluated expression given by expr. Evaluated expressions of a string type are in a case insensitive alphabetical order. If multiple -sort arguments appear on the command line, the primary sort will be on the leftmost one within the command line, and it is numbered 0. A secondary sort will be based on the second expression, and it is numbered 1. For informational or debugging purposes, the ClassAd output to be displayed will appear as if the ClassAd had two additional attributes. CondorStatusSortKeyExpr<N> is the expression, where <N> is replaced by the number of the sort. CondorStatusSortKey<N> gives the result of evaluating the sort expression that is numbered <N>.

-total

(Display option) Display totals only.

-xml

(Display option) Display entire ClassAds, in XML format. The XML format is fully defined in the reference manual, obtained from the ClassAds web page, with a link at http://htcondor.org/classad/classad.html.

-json

(Display option) Display entire ClassAds in JSON format.

-constraint const

(Custom option) Add constraint expression.

-compact 

(Custom option) Show compact form, rolling up slots into a single line.

-format fmt attr

(Custom option) Display attribute or expression attr in format fmt. To display the attribute or expression the format must contain a single printf(3)-style conversion specifier. Attributes must be from the resource ClassAd. Expressions are ClassAd expressions and may refer to attributes in the resource ClassAd. If the attribute is not present in a given ClassAd and cannot be parsed as an expression, then the format option will be silently skipped. %r prints the unevaluated, or raw values. The conversion specifier must match the type of the attribute or expression. %s is suitable for strings such as Name, %d for integers such as LastHeardFrom, and %f for floating point numbers such as LoadAvg. %v identifies the type of the attribute, and then prints the value in an appropriate format. %V identifies the type of the attribute, and then prints the value in an appropriate format as it would appear in the -long format. As an example, strings used with %V will have quote marks. An incorrect format will result in undefined behavior. Do not use more than one conversion specifier in a given format. More than one conversion specifier will result in undefined behavior. To output multiple attributes repeat the -format option once for each desired attribute. Like printf(3)-style formats, one may include other text that will be reproduced directly. A format without any conversion specifiers may be specified, but an attribute is still required. Include a backslash followed by an ‘n’ to specify a line break.

-autoformat[:lhVr,tng] attr1 [attr2 ...] or -af[:lhVr,tng] attr1 [attr2 ...]

(Output option) Display attribute(s) or expression(s) formatted in a default way according to attribute types. This option takes an arbitrary number of attribute names as arguments, and prints out their values, with a space between each value and a newline character after the last value. It is like the -format option without format strings. This output option does not work in conjunction with the -run option.

It is assumed that no attribute names begin with a dash character, so that the next word that begins with dash is the start of the next option. The autoformat option may be followed by a colon character and formatting qualifiers to deviate the output formatting from the default:

l label each field,

h print column headings before the first line of output,

V use %V rather than %v for formatting (string values are quoted),

r print "raw", or unevaluated values,

, add a comma character after each field,

t add a tab character before each field instead of the default space character,

n add a newline character after each field,

g add a newline character between ClassAds, and suppress spaces before each field.

Use -af:h to get tabular values with headings.

Use -af:lrng to get -long equivalent format.

The newline and comma characters may not be used together. The l and h characters may not be used together.

-target filename

(Custom option) Where evaluation requires a target ClassAd to evaluate against, file filename contains the target ClassAd.

-merge filename

(Custom option) Ads will be read from filename, which may be - to indicate standard in, and compared to the ads selected by the query specified by the remainder of the command line. Ads will be considered the same if their sort keys match; sort keys may be specified with [-sort  <key>]. This option will cause up to three tables to print, in the following order, depending on where a given ad appeared: first, the ads which appeared in the query but not in filename; second, the ads which appeared in both the query and in filename; third, the ads which appeared in filename but not in the query.

By default, banners will label each table. If -xml is also given, the same banners will separate three valid XML documents, one for each table. If -json is also given, a single JSON object will be produced, with the usual JSON output for each table labeled as an element in the object.

The -annex option changes this default so that the banners are not printed and the tables are formatted differently. In this case, the ads in filename are expected to have different contents from the ads in the query, so many others will behave strangely.

General Remarks

• The default output from condor_status is formatted to be human readable, not script readable. In an effort to make the output fit within 80 characters, values in some fields might be truncated. Furthermore, the HTCondor Project can (and does) change the formatting of this default output as we see fit. Therefore, any script that is attempting to parse data from condor_status is strongly encouraged to use the -format option (described above).
• The information obtained from condor_startd and condor_schedd daemons may sometimes appear to be inconsistent. This is normal since condor_startd and condor_schedd daemons update the HTCondor manager at different rates, and since there is a delay as information propagates through the network and the system.
• Note that the ActivityTime in the Idle state is not the amount of time that the machine has been idle. See the section on condor_startd states in the Administrator’s Manual for more information (section 3.2).
• When using condor_status on a pool with SMP machines, you can either provide the host name, in which case you will get back information about all slots that are represented on that host, or you can list specific slots by name. See the examples below for details.
• If you specify host names, without domains, HTCondor will automatically try to resolve those host names into fully qualified host names for you. This also works when specifying specific nodes of an SMP machine. In this case, everything after the “@” sign is treated as a host name and that is what is resolved.
• You can use the -direct option in conjunction with almost any other set of options. However, at this time, the only daemon that will allow direct queries for its ad(s) is the condor_startd. So, the only options currently not supported with -direct are -schedd and -master. Most other options use startd ads for their information, so they work seamlessly with -direct. The only other restriction on -direct is that you may only use 1 -direct option at a time. If you want to query information directly from multiple hosts, you must run condor_status multiple times.
• Unless you use the local host name with -direct, condor_status will still have to contact a collector to find the address where the specified daemon is listening. So, using a -pool option in conjunction with -direct just tells condor_status which collector to query to find the address of the daemon you want. The information actually displayed will still be retrieved directly from the daemon you specified as the argument to -direct.

Examples

Example 1 To view information from all nodes of an SMP machine, use only the host name. For example, if you had a 4-CPU machine, named vulture.cs.wisc.edu, you might see

Example 2 To view information from a specific nodes of an SMP machine, specify the node directly. You do this by providing the name of the slot. This has the form slot#@hostname. For example:

Constraint option examples

The Unix command to use the constraint option to see all machines with the OpSys of "LINUX":

Note that quotation marks must be escaped with the backslash characters for most shells.

The Windows command to do the same thing:

Note that quotation marks are used to delimit the single argument which is the expression, and the quotation marks that identify the string must be escaped by using a set of two double quote marks without any intervening spaces.

To see all machines that are currently in the Idle state, the Unix command is

To see all machines that are bench marked to have a MIPS rating of more than 750, the Unix command is

-cod option example

The -cod option displays the status of COD claims within a given HTCondor pool.

-format option example To display the name and memory attributes of each job ClassAd in a format that is easily parsable by other tools:

To do the same with the autoformat option, run

Exit Status

condor_status will exit with a status value of 0 (zero) upon success, and it will exit with the value 1 (one) upon failure.
