Monitoring for jitsi meet

- Therefore split telegraf into two instances one for host and docker and other for network queries (network monitoring)

+# Telegraf Configuration
+#
+# Telegraf is entirely plugin driven. All metrics are gathered from the
+# declared inputs, and sent to the declared outputs.
+#
+# Plugins must be declared in here to be active.
+# To deactivate a plugin, comment out the name and any variables.
+#
+# Use 'telegraf -config telegraf.conf -test' to see what metrics a config
+# file would generate.
+#
+# Environment variables can be used anywhere in this config file, simply surround
+# them with ${}. For strings the variable must be within quotes (ie, "${STR_VAR}"),
+# for numbers and booleans they should be plain (ie, ${INT_VAR}, ${BOOL_VAR})
+
+# Config Sample under https://github.com/influxdata/telegraf/blob/master/etc/telegraf.conf
+
+# Global tags can be specified here in key="value" format.
