From 2430bad8951a321e0fcb50eafb562ecbdbecbb5b Mon Sep 17 00:00:00 2001 From: Alexander Chernavin Date: Fri, 17 Sep 2021 12:37:48 +0000 Subject: stats: add name vectors to prometheus exporter output Type: improvement Counters are labeled with interface indices in the Prometheus exporter output. For example: # TYPE _if_drops counter _if_drops{thread="0",interface="0"} 0 _if_drops{thread="0",interface="1"} 0 _if_drops{thread="0",interface="2"} 2112 [..] Currently, it's unable to map interface indices to the interface names using only output provided by the Prometheus exporter. However, this mapping is present in the vpp_get_stats output: # vpp_get_stats dump /if/names [0]: local0 /if/names [1]: GigabitEthernet0/8/0 /if/names [2]: GigabitEthernet0/9/0 /if/names [..] With this change, add name vectors to Prometheus exporter output as info metrics. Thus exposing interfaces and their indices: # TYPE _if_names_info gauge _if_names_info{index="0",name="local0"} 1 _if_names_info{index="1",name="GigabitEthernet0/8/0"} 1 _if_names_info{index="2",name="GigabitEthernet0/9/0"} 1 [..] Signed-off-by: Alexander Chernavin Change-Id: Iff86c4d6fea8805e71fb04fccf278bae855e88d1 --- src/vpp/app/vpp_prometheus_export.c | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'src') diff --git a/src/vpp/app/vpp_prometheus_export.c b/src/vpp/app/vpp_prometheus_export.c index 99944917766..e2bd9521a2f 100644 --- a/src/vpp/app/vpp_prometheus_export.c +++ b/src/vpp/app/vpp_prometheus_export.c @@ -112,6 +112,15 @@ retry: res[i].scalar_value); break; + case STAT_DIR_TYPE_NAME_VECTOR: + fformat (stream, "# TYPE %s_info gauge\n", + prom_string (res[i].name)); + for (k = 0; k < vec_len (res[i].name_vector); k++) + if (res[i].name_vector[k]) + fformat (stream, "%s_info{index=\"%d\",name=\"%s\"} 1\n", + prom_string (res[i].name), k, res[i].name_vector[k]); + break; + case STAT_DIR_TYPE_EMPTY: break; -- cgit 1.2.3-korg
