I've found a high number of failures in output of `vmstat -z` in category of "NetGraph data items". Trying to monitor those failures I see that they increase in short moments and stay at the level for longer. It's like NetGraph data items: 36, 546, 1, 545, 514855314626, 1247384311 NetGraph data items: 36, 546, 6, 540, 514855480968, 1247384311 NetGraph data items: 36, 546, 5, 541, 514855721631, 1247384311 NetGraph data items: 36, 546, 507, 39, 514857074684, 1247384437 NetGraph data items: 36, 546, 22, 524, 514857862740, 1247384443 with a second between consecutive lines.
It looks like I need to raise net.graph.maxdata from a default of 512. What are the safe values for this tunable cause it carries comment of "limit the damage of a DoS"? What kind of DoS is it about? -- Eugene Perevyazko _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[email protected]"
