Hi, Lately I'm running into problems with my pmacct instance which I can't seem to pinpoint. I've been running pmacct for a couple of years now, but lately with increased traffic load these error messages started popping up.
Nov 12 11:20:19 traffic-tap02 pmacctd[10959]: ERROR ( in/mysql ): We are missing data. Nov 12 11:20:19 traffic-tap02 pmacctd[10959]: If you see this message once in a while, discard it. Otherwise some solutions follow: Nov 12 11:20:19 traffic-tap02 pmacctd[10959]: - increase shared memory size, 'plugin_pipe_size'; now: '65536000'. Nov 12 11:20:19 traffic-tap02 pmacctd[10959]: - increase buffer size, 'plugin_buffer_size'; now: '32768'. Nov 12 11:20:19 traffic-tap02 pmacctd[10959]: - increase system maximum socket size.#012 I tried increasing the parameters in the error message but nothing seems to help. I'm new to the list, hoping someone can help me or had similar problems. Is there a formula to calculate the ideal values for these parameters under a certain load? My setup: Two 10gig interfaces. Interface1: About 1Gbit traffic and 1239374 packets /sec Interface2: About 1Gbit traffic and 874745 packets /sec The load on the Linux box is really low, never passing 1.0 My pmacct configuration for interface1: ! ! pmacct: Out (Traffic from the DC to Internet) ! debug: true daemonize: true interface: eth1 plugin_buffer_size: 32768 plugin_pipe_size: 131072000 pidfile: /var/run/pmacctd-out.pid syslog: local6 post_tag: 1 ! plugins: mysql[out] ! networks_file[out]: /usr/local/pmacct/etc/networks.def aggregate[out]: tag,src_host ! sql_host[out]: x.x.x.x sql_user[out]: pmacct sql_passwd[out]: password sql_db[out]: pmacct sql_recovery_backup_host[out]: 127.0.0.1 ! sql_table[out]: acct_v2_out_%Y%m%d sql_optimize_clauses[out]: true sql_table_schema[out]: /usr/local/pmacct/etc/acct_custom_out.schema ! sql_history[out]: 5m sql_history_roundoff[out]: m sql_refresh_time[out]: 300 sql_dont_try_update[out]: true sql_multi_values[out]: 16000000 Hope anyone can help.
