NAME

ns_info - Return information about various aspects of the running AOLserver

SYNOPSIS

ns_info option

DESCRIPTION

This command provides information about the current state of the running AOLserver. The legal options (which may be abbreviated) are:

• ns_info address

returns the primary IP address of this machine, or "0.0.0.0" if unable to determine

• ns_info argv0

returns the currently running nsd binary as launched and prior to normalizing path

• ns_info boottime

returns the time in epoch seconds since the current server was started

• ns_info builddate

returns the date and time at which the current server was compiled, e.g.: "Jul 20 2004 at 14:57:20"

• ns_info callbacks

returns a list of all registered startup, pre-startup, shutdown, server shutdown, exit, and SIGHUP signal procs (e.g. scripts registered for SIGHUP with ns_atsignal). Each list element is itself a 3-element list like this:

{shutdown logclose d:/AOLserver/servers/server1/modules/nslog/access1.log}

• ns_info config

returns the absolute path to the config file used to start the server

• ns_info home

returns the current working directory of the server

• ns_info hostname

returns the value of gethostname(), or "localhost" if that fails

• ns_info label

returns the value of NSD_LABEL from nsd.h, e.g. "aolserver4_0"

• ns_info locks

lists the mutexes that currently exist. A 5-element list is returned for each mutex: mutex name, {}, unique id, lock counter, busy counter

• ns_info log

returns the name of the error log specified by the "serverlog" parameter in the "ns/parameters" section, or "server.log" if not defined. Prepends the server's current working directory

• ns_info major

returns the value of NS_MAJOR_VERSION from ns.h, e.g. "4"

• ns_info minor

returns the value of NS_MINOR_VERSION from ns.h, e.g. "0"

• ns_info name

returns the value of NSD_NAME from nsd.h (currently 'AOLserver')

• ns_info nsd

returns the absolute path to the currently running nsd binary

• ns_info pageroot

returns the absolute path to the page root

• ns_info patchlevel

returns the value of NS_PATCH_LEVEL from ns.h, e.g. "4.0.7"

• ns_info pid

returns the process ID of the current nsd process

• ns_info platform

returns the name of the current platform, or "?" if unable to determine

• ns_info pools

returns the results of Tcl_GetMemoryInfo() function if exported by the Tcl build

• ns_info scheduled

returns a list of all scheduled tasks in the current process (all virtual servers). Each list element is itself a 9-element list of {id, flags, interval, nextqueue, lastqueue, laststart, lastend, procname, arg}:

• id - unique id returned by the scheduling command
• flags - Bitmap of one or more of:
  • 1 -- NS_SCHED_THREAD
  • 2 -- NS_SCHED_ONCE
  • 4 -- NS_SCHED_DAILY
  • 8 -- NS_SCHED_WEEKLY
  • 16 - NS_SCHED_PAUSED
  • 32 - NS_SCHED_RUNNING
• interval - interval specification (i.e. seconds from midnight for daily schedule)
• nextqueue - Next time to queue for run
• lastqueue - Last time queued for run
• laststart - Last time run started
• lastend - Last time run finished
• procname - for tasks scheduled with ns_schedule_proc this will be ns:tclschedproc and arg will be the actual scheduled tcl script.
• arg - client data

Example:

{4 4 10800 1254650400 1254564000 1254564000 1254564004 logroll d:/AOLserver/servers/dncscrub1/modules/nslog/access.log}

• ns_info server

returns the name of the current virtual server. During the bootstrap process, when processing the config file, ns_info server returns the value of the -s parameter in AOLserver builds after 2004-12-02.

• ns_info servers

returns a list of virtual servers in the current nsd process

• ns_info sockcallbacks

returns a list of all socket callbacks such as the socket listening callback for the nscp module. Each list element is itself a 4-element list like this:

{540 {read exit} nscp {127.0.0.1 9999}}

• ns_info tag

returns the CVS tag (NSD_TAG from nsd.h); not guaranteed to be useful

• ns_info tcllib

returns the path the virtual server's private tcl library - identical to [[[ns_library]] private]

• ns_info threads

returns a list of all threads in the current process (all virtual servers). Each list element is itself a 7-element list of {name, parent, id, flag, ctime, procname, arg}:

• name - current name of the thread
• parent - parent thread name
• id - id of the thread
• flag - 1 if this is a detached thread, 0 otherwise
• ctime - Thread creation time
• procname - for conn threads this will be ns:connthread
• arg - client data - for a running conn thread arg will be a 7-element list in the format returned by ns_server all - {conn id, peeraddr, state, method, url, running time, bytes sent}, where state is either "running" or "queued":

{-default:3- -nssock:driver- 15480 0 1254437214 ns:connthread {3536 192.168.0.1 running GET /_stats 0.15624 0}}

Note that running time is returned in seconds.microseconds format which is misleading because 0.100 does not mean a tenth of a second, it means 100 microseconds.

• ns_info uptime

returns the number of seconds since the process started

• ns_info version

returns the major.minor version string (i.e. 4.5)

• ns_info winnt

returns 1 if the platform is Windows, 0 otherwise
