IPHost SNMP Traps Monitor – Network Servers Monitoring

SNMP (Simple Network Management Protocol) Monitor is an advanced type of monitor. SNMP is commonly used to access and/or change various variables of a network device. That includes computers running almost any type of OS; network equipment such as routers and almost every other type of IP-enabled devices.

Common approach is to request (poll) SNMP information from agent (the device running SNMP service). Polling can be used when scheduled data request is required, when data are necessary to update at known time intervals. However, if an event requiring immediate attention happens, it can only be noticed when another polling occurs. Setting polling too frequently would waste bandwidth and create additional load on SNMP agent.

In such a case SNMP traps can be used. Simple speaking, trap is a signal sent from SNMP agent to SNMP manager (i.e., IPHost Network Monitor), without manager requesting it. That makes it possible to get informed of certain actions almost immediately. Manual SNMP trap processing would require writing a special script listening for incoming connection; IPHost does that all for you.

SNMP trap monitor isn’t polled; it’s a passive (listening) type of monitor. It is called by host being monitored and thus remains in unknown state until first called. To set up such monitor, follow corresponding online help instructions. To find information on variables you could use, check MIB database.

Since SNMP traps can be software-initiated, they are ideal for immediate notifications. One can also pass pieces of information along with SNMP trap (so called payload), which can be recognized on IPHost Network Monitor side and reacted to as required. Consider using SNMP traps to get warned about sudden mail service shutting down, or disk space running low etc.

Custom SNMP monitors should still be used when regular data acquisition is required, to get periodically updated statistics.

Note: SNMP trap monitor listens for UDP packets on well known port (162) and thus the port should be open (in case firewall or other network filter is used).
