Command line | Registry
MaxKeepAliveRequests sets the maximum number of HTTP/HTTPS
requests that the uploader component (in either FlexNet inventory agent or FlexNet Beacon) may make on a given persistent HTTP/HTTPS connection. Effectively, this is
the number of file uploads attempted before requesting a new connection. The count monitors
only uploads (for example, of inventory or discovery files, status reports or logs) and is not
affected by downloads (for example, of policy or self-update packages).Tip: This setting, which limits the reuse of
HTTP/HTTPS connections, is independent of socket-level keep-alive requests that are
controlled by SendTCPKeepAlive. Both may operate across the same
network connection: for example, when the uploader switches connections to start uploading a
distinct file type, this setting may render an older connection unavailable. Otherwise, the
settings are independent.
The special value MaxKeepAliveRequests=0 means that there is no maximum, and
the uploader issues keep-alive requests repeatedly (uses the same connection for all file
uploads). The same result occurs if you manually remove the registry setting.
The main benefit of limiting the number of requests on a persistent connection is to allow
for improved load balancing across large systems. Because load balancers do not re-route
persistent connections, dropping the connection and requesting a new one allows for improved
load balancing between multiple servers.
Tip: This
MaxKeepAliveRequests setting works in conjunction with MaxKeepAliveLifetime. If both settings are active, a new
HTTP/HTTPS connection is requested (and both counters are reset) for the next upload after
either of these limits is reached.Values
