聚合的 munin 图表文件为空

聚合的 munin 图表文件为空

我无法聚合我编写的一些自定义图表。我知道聚合是可行的,因为我能够聚合默认插件,但我不确定我的插件出了什么问题。

munin.conf:

[myapp;web-servers;0-1]
        address 1.2.3.4
        use_node_name yes
[myapp;web-servers;0-2]
        address 5.6.7.8
        use_node_name yes

[myapp;web-servers;Aggregated]
        update no

#does not work:
    node_aggregate.graph_args --base 1000 -l 0
    node_aggregate.graph_title Aggregated connects
    node_aggregate.conns.label conns
    node_aggregate.conns.sum myapp;web-servers;0-1:nodejs_numberOfConnects.conns myapp;web-servers;0-2:nodejs_numberOfConnects.conns


#works:
    node_aggregate.graph_title Aggregated cpu
    node_aggregate.cpu.label cpu.user
    node_aggregate.cpu.sum myapp;web-servers;0-1:cpu.user myapp;web-servers;0-2:cpu.user

我的插件如下所示:

if [[ "$PARAM" == "numberOfConnects" ]]; then
        echo "graph_title Active Connects";
        echo "graph_info Active Connects";
        echo "graph_vlabel Connections";
        echo "$PARAM.label conns";
        echo "$PARAM.type GAUGE";
        echo "$PARAM.colour 0927EB"
        exit 0;
elif ...
fi
echo $PARAM.value 15

为了测试目的,我可以硬编码“$PARAM.value 15”。然后我可以执行
munin-run --servicedir /etc/munin/plugins nodejs_numberOfConnects此操作,这将返回numberOfConnects.value 15

我得到的错误是:

==> /var/log/munin/munin-graph.log <==
2016/03/15 13:57:01 [ERROR] filename is empty for $VAR1 = {
  '#%#name' => 'z1_0',
  'cdef' => 'z1_0,UN,0,z1_0,IF',
  'graph' => 'no',
  'label' => 'z1_0'
};
, myapp;web-servers;0-1:nodejs_numberOfConnects.conns

2016/03/15 13:57:01 [ERROR] filename is empty for $VAR1 = {
  '#%#name' => 'z1_1',
  'cdef' => 'z1_1,UN,0,z1_1,IF,z1_0,ADDNAN',
  'colour' => undef,
  'draw' => undef,
  'graph' => 'yes',
  'label' => 'conns'
};
, myapp;web-servers;0-2:nodejs_numberOfConnects.conns

答案1

您正在尝试通过康纳斯作为导出的值,但实际上连接数

node_aggregate.nodejs_numberOfConnects.label conns(or whatever)
node_aggregate.nodejs_numberOfConnects.sum \ 
    myapp;web-servers;0-1:nodejs_numberOfConnects.numberOfConnects \ 
    myapp;web-servers;0-2:nodejs_numberOfConnects.numberOfConnects

答案2

经过多次调试后,我意识到我错误地使用了标签而不是名称价值

node_aggregate.conns.sum myapp;web-servers;0-1:nodejs_numberOfConnects.conns myapp;web-servers;0-2:nodejs_numberOfConnects.conns

需要是

node_aggregate.conns.sum myapp;web-servers;0-1:nodejs_numberOfConnects.numberOfConnects myapp;web-servers;0-2:nodejs_numberOfConnects.numberOfConnects

因为

if [[ "$PARAM" == "numberOfConnects" ]]; then
[...]
echo $PARAM.value 15

换句话说,在我的例子中,服务器行等于:
$arbitraryname1.arbitraryname2.sum $clientname;$hostgroup;$hostname:$pluginname.$valuename

cpu我还对使用以下语法的示例感到非常困惑:
myapp;web-servers;0-1:cpu.user但那是因为它的值名称实际上与标签名称一致!
