[MAJOR] proto_uxst rework -> SNMP support Currently there is a ~16KB limit for a data size passed via unix socket. It is caused by a trivial bug ttat is going to fixed soon, however in most cases there is no need to dump a full stats. This patch makes possible to select a scope of dumped data by extending current "show stat" to "show stat [<iid> <type> <sid>]": - iid is a proxy id, -1 to dump all proxies - type selects type of dumpable objects: 1 for frontend, 2 for backend, 4 for server, -1 for all types. Values can be ORed, for example: 1+2=3 -> frontend+backend. 1+2+4=7 -> frontend+backend+server. - sid is a service id, -1 to dump everything from the selected proxy. To do this I implemented a new session flag (SN_STAT_BOUND), added three variables in data_ctx.stats (iid, type, sid), modified dumpstats.c and completely revorked the process_uxst_stats: now it waits for a "\n" terminated string, splits args and uses them. BTW: It should be quite easy to add new commands, for example to enable/disable servers, the only problem I can see is a not very lucky config name (*stats* socket). :| During the work I also fixed two bug: - s->flags were not initialized for proto_uxst - missing comma if throttling not enabled (caused by a stupid change in "Implement persistent id for proxies and servers") Other changes: - No more magic type valuse, use STATS_TYPE_FE/STATS_TYPE_BE/STATS_TYPE_SV - Don't memset full s->data_ctx (it was clearing s->data_ctx.stats.{iid/type/sid}, instead initialize stats.sv & stats.sv_st (stats.px and stats.px_st were already initialized) With all that changes it was extremely easy to write a short perl plugin for a perl-enabled net-snmp (also included in this patch). 29385 is my PEN (Private Enterprise Number) and I'm willing to donate the SNMPv2-SMI::enterprises.29385.106.* OIDs for HAProxy if there is nothing assigned already.
