monitor

[Please suggest content for the Short Description, to summarise and introduce this topic. What does the command do, and what does this topic show?]

The monitor operational command tree contains many user-accessible debugging utilities. These include protocol logging and system debugging functions.

When you enable extra logging, remember that this increases the load on the the system. If the system is already under a heavy load then the extra logging may overload the system. In such an environment, consider alternatives:

  • Schedule extra logging to take place during a maintenance period
  • Test the effects of extra logging on your non-production test system before you enable it on your production system

Example: monitor

$OS_PROMPT$ monitor
Possible completions:
arp Monitor Address Resolution Protocol (ARP)
bonding Monitor bonded interface events
command Monitor an operational mode command (refreshes every 2 seconds)
dataplane Monitor dataplane packet performance
dhcp Monitor Dynamic Host Control Protocol (DHCP)
dns Monitor a Domain Name Service (DNS) daemon
firewall Monitor firewall
https Monitor the Secure Hypertext Transfer Protocol (HTTPS) service
interfaces Monitor interfaces
ip-traffic Monitor ip traffic
log Monitor last lines of the system log
ndp Monitor IPv6 Neighbor Discovery Protocol (NDP)
openvpn Monitor OpenVPN
path-monitor Monitor the Path Monitor service
policy <No help text available>
protocol Monitor routing protocols
queuing Monitor dataplane queues
snmp Monitor Simple Network Management Protocol (SNMP) daemon
traceroute Monitor the path to a destination in realtime
vpn Monitor VPN
vrrp Monitor Virtual Router Redundancy Protocol (VRRP)

Example: monitor protocol bgp

This example demonstrates the command tree for a more verbose Border Gateway Protocol (BGP) daemon. After you increase the verbosity you will find extra messages for BGP in your system log. These will help you to troubleshoot BGP-related issues.

$OS_PROMPT$ monitor protocol bgp
Possible completions:
disable Disable BGP debugging
enable Enable BGP debugging
routing-instance BGP routing instance debugging
$OS_PROMPT$ monitor protocol bgp enable
Possible completions:
<Enter> Execute the current command
<h:h:h:h:h:h:h:h> IPv6 Address
<x.x.x.x> IPv4 Address
additional-paths Enable BGP Additional Paths debugging
all Enable all BGP debugging
auth Enable BGP Authentication debugging
bfd Enable BGP BFD debugging
dampening Enable BGP dampening debugging
events Enable BGP events debugging
filters Enable BGP filters debugging
fsm Enable BGP Finite State Machine (FSM) debugging
graceful-restart Enable BGP Graceful restart debugging
keepalives Enable BGP keepalives debugging
mpls Enable BGP MPLS debugging
msdp Enable BGP MSDP debugging
nexthop-tracking Enable BGP nexthop tracking debugging
rib Enable BGP RIB debugging
rtfilter Enable BGP RT Filter debugging
