Syslog monitoring is the collection and analysis of system and network device messages generated by infrastructure such as routers, switches, servers, security systems, and other devices.
Syslog monitoring is the collection and analysis of system and network device messages generated by infrastructure such as routers, switches, servers, security systems, and other devices.
These messages record operational events that can help administrators understand what occurred within the network.
Devices generate syslog messages when operational events occur. Depending on the device, events may include:
A centralized monitoring system can collect these messages from multiple devices.
Network metrics tell administrators what a device is doing. Logs can provide additional information about events occurring around the same time.
For example, if an interface unexpectedly goes down, administrators may examine:
Combining these sources can make troubleshooting faster.
Syslog and SNMP provide different types of visibility. SNMP monitoring generally polls devices for operational measurements. Syslog monitoring receives event messages generated by devices.
SNMP may show that an interface is down. A syslog message may provide additional information about the event that occurred.
When every network device stores events independently, administrators may need to access many systems during an investigation. Centralized syslog monitoring brings messages from multiple devices into a common environment.
This makes it easier to review events across infrastructure and identify related activity.
FatPipe Constellation includes syslog monitoring within its network monitoring and reporting capabilities. Syslog information can be reviewed alongside other network information such as device status, interfaces, traffic, SNMP information, topology, and alerts.
Many routers, switches, servers, firewalls, and other infrastructure devices can generate syslog messages.
Syslog is primarily an event logging and message transport standard rather than a device polling protocol.
SNMP provides device measurements while syslog provides event information. Combining them can provide additional troubleshooting context.
