Question

团队，

我创建了一个警报，并且该警报正在运行，但是我需要将其用于两个值。任何提示我如何在消息之间使用OR运算符？当我删除条件后，它就会按预期工作。

工作表达

message: 'Node {{ `{{ $labels.nodename }}` }} was rebooted'

无效的表达式

message: 'Node {{- if or `{{ $labels.nodename }}` `{{ $labels.node }}` }} was rebooted {{- end }}'

    - alert: NodeReboot
      annotations:
        message: 'Node {{- if or `{{ $labels.nodename }}` `{{ $labels.node }}` }} was rebooted {{- end }}'
        runbook_url: TODO
      expr: (time() - node_boot_time_seconds)/60 < 15
      for: {{ .Values.genericAlerts.alertDefinitions.NodeReboot.for }}
      {{- if .Values.genericAlerts.alertDefinitions.NodeReboot.labels }}
      labels:
{{ toYaml .Values.genericAlerts.alertDefinitions.NodeReboot.labels | indent 8 }}
      {{- end }}
    {{- end }}
    {{- if .Values.genericAlerts.alertDefinitions.GpuNodeMissingPowerLabel.enabled }}

输出：

- alert: NodeReboot
    annotations:
    message: 'Node was rebooted'

预期

- alert: NodeReboot
    annotations:
    message: 'Node test-node1 was rebooted'

如果只打印其中之一，请使用以下条件。

#include <stdio.h>
#include <stdlib.h>

#define STACKSIZE 1000

struct stack  
{
    int top;
    char items[STACKSIZE];
};

void push(struct stack *pb, char x)
{
    if(pb->top==STACKSIZE)
        printf("The stack is full\n");
    else
        pb->items[pb->top++]=x;
}


int main()
{
    while(1)
    {
        struct stack balance;     //the stack called "balance"
        struct stack *b;          //the pointer of stack
        char line[STACKSIZE];     //input
        scanf("%s", line);

        if(!strcmp(line, "-1"))   //program stops when only "-1"
            break;

        b->top=0;                 //initializing top value

        for(int i=0;i<STACKSIZE-1;i++)        
        {
            if(line[i]=='(' || line[i]==')')      //push '(' and ')' in the input to the stack
                push(b, line[i]);
        }
        printf("test");           //can't reach this line
        printf("%s\n", b->items);

    }

    return 0;
}

如果您都不想设置message: 'Node {{ if $labels.nodename }}{{ $labels.nodename }}{{ else if $labels.node }}{{ $labels.node }}{{ end }} was rebooted'，而又不想打印，请添加以下IF条件。

was rebooted
