Ns limits

NAME

ns_limits - Resource management via limit sets

SYNOPSIS

ns_limits option ?arg arg ...?

DESCRIPTION

This command command enables setting various resource limits for specified method/url combinations. These limits include such items as max concurrent connections, max file upload size, and timeouts waiting for connection processing. When limits are exceeded, connections are immediately dispatched to a dedicated error pool connection processing pool to generate a quick error response. By default all requests share the same default limits. Coupled with the new "ns_pools" command, URL-based limits can provide for sophisticated resource management.

This command can be used to set to retrieve various pieces of information about a pool configuration.

• ns_limits set limit-set ? -maxrun value? ? -maxwait value? ? -maxupload value? ? -timeout value?

Configure the specified limit-set with the given values. maxrun specifies the maximum number of connections which can be running simultaneously bound to the limit-set (default 100). maxwait specifies the maximum number of connections waiting, when no connection thread is available (default 100). maxupload is the maximum size of a PUT or POST request (default: 10 MB), timeout is the maximum number of seconds to wait to be run before being overflown to the error pool (default 60).

• ns_limits get limit-set

Returns a map (list of attribute value pairs in array get format) for the specified limit-set (e.g. default). The command returns values for the following attributes nrunning, nwaiting, ntimeout, ndropped, noverflow, maxwait, maxupload, timeout and maxrun
