Syslog heartbeat and monitoring <p>Does anybody know how or even if, since I can't locate much on it, syslog offers any heartbeat mechanism?</p> <p>I'm specifically thinking about how to monitor the devices that offer up syslog messages. </p> <p>I'm not specifically looking to use an external solution, but instead something syslog possibly offers itself, which can be monitored/interrogated and flagged if something is down. </p> <p>Or is their a standard lightweight tcp-based heartbeat protocol which runs on win/linux/bsd/solaris/aix/hp-ux?</p>
