NAME
- ns_limits - Resource management via limit sets (new in AOLserver 4.5)
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
- ns_limits list ?pattern?
- Returns a list of the configured resource limit-sets optionally matching glob pattern in ?pattern?. AOLserver creates a default limit-set called default
- ns_limits register limit-set server method url
- Register limit-set for requests issued to the specified server, HTTP method and url
EXAMPLES
- ns_limits get default
