From 186f4a33fea210e63ef25b023adab9abf133004d Mon Sep 17 00:00:00 2001 From: Andrew Hayworth Date: Mon, 19 Oct 2015 19:15:56 +0000 Subject: [PATCH] MINOR: cli: ability to set per-server maxconn This commit adds support for setting a per-server maxconn from the stats socket. The only really notable part of this commit is that we need to check if maxconn == minconn before changing things, as this indicates that we are NOT using dynamic maxconn. When we are not using dynamic maxconn, we should update maxconn/minconn in lockstep. --- src/dumpstats.c | 31 ++++++++++++++++++++++++++++++- 1 file changed, 30 insertions(+), 1 deletion(-) diff --git a/src/dumpstats.c b/src/dumpstats.c index e80e45c..b2bd13b 100644 --- a/src/dumpstats.c +++ b/src/dumpstats.c @@ -1646,6 +1646,35 @@ static int stats_sock_parse_request(struct stream_interface *si, char *line) return 1; } + else if (strcmp(args[2], "server") == 0) { + struct server *sv; + int v; + + sv = expect_server_admin(s, si, args[3]); + if (!sv) + return 1; + + if (!*args[4]) { + appctx->ctx.cli.msg = "Integer value expected.\n"; + appctx->st0 = STAT_CLI_PRINT; + return 1; + } + + v = atoi(args[4]); + if (v < 0) { + appctx->ctx.cli.msg = "Value out of range.\n"; + appctx->st0 = STAT_CLI_PRINT; + return 1; + } + + if (sv->maxconn == sv->minconn) { // static maxconn + sv->maxconn = sv->minconn = v; + } else { // dynamic maxconn + sv->maxconn = v; + } + + return 1; + } else if (strcmp(args[2], "global") == 0) { int v; @@ -1681,7 +1710,7 @@ static int stats_sock_parse_request(struct stream_interface *si, char *line) return 1; } else { - appctx->ctx.cli.msg = "'set maxconn' only supports 'frontend' and 'global'.\n"; + appctx->ctx.cli.msg = "'set maxconn' only supports 'frontend', 'server', and 'global'.\n"; appctx->st0 = STAT_CLI_PRINT; return 1; } -- 2.1.3
