Port Time outs on Remote Hosts
I monitor all my servers using Nagios. Now, for Nagios to run certain checks, it has to connect to remote hosts via a certain port. Lets say the port is 8090.
Now, when Nagios connects to a remote host (for an example) via port 8090, and it has to run 6 checks (scripts) on that remote host, i find that it times out. Because, those 6 checks, depending on how quickly they finish up, can consume the port.
my question is, how can i make it so that a port can accept the maximum number of connections and can uphold those connections until the scripts finish?
i mean, say i have 15 requests/connections that are being sent from one central location to port 8090 on a remote host, what setting is it that determines how many connections/request port 8090 on that remote host can handle before it starts dropping them?

MAILPING-LATENCY(1) Mailping MAILPING-LATENCY(1)
NAME
mailping-latency - Munin plugin to graph latency of mail deliveries
SYNOPSIS
/usr/share/mailping/munin-plugins/mailping-latency {[config] | ['']}
DESCRIPTION
mailping-latency is a Munin plugin that monitors the time spent between email submit and it's delivery.
Configuration output
When passed config, it outputs Munin configuration information. If there are no circuits defined (no subdirectories in /etc/mailping), it
specifies that Munin should draw no graph either.
If configuration files /etc/mailping/circuit/warnlatency and /etc/mailping/circuit/faillatency exist, the values in them are passed on to
Munin, for use in Nagios alert integration.
Value output
When passed an empty string '', mailping-latency outputs latency of last successful probe message, for each configured circuit.
FILES
/etc/mailping/
List of circuits that exist; each subdirectory is a circuit.
/etc/mailping/circuit/warnlatency
If latency is greater than this many seconds, a Nagios warning is triggered by Munin (assuming it has been configured to do that).
Default: no warnings.
/etc/mailping/circuit/faillatency
If latency is greater than this many seconds, a Nagios alert is triggered by Munin (assuming it has been configured to do that).
Default: no alerts.
/var/lib/mailping/state/circuit/latency
Amount of latency in seconds of the last successful probe for circuit.
ENVIRONMENT
MAILPING_CONFIGDIR
Override the location of the configuration directory. Default: /etc/mailping
MAILPING_STATEDIR
Override the location of the state directory. Circuit states are stored in the state subdirectory of this directory, in subdirectories
named after the circuit name. Default: /var/lib/mailping
