jq: Erstellen eines Filters für CSV-Ausgabe

Ich habe die folgende JSON-Datei:

{
"result": [
{
  "hostid": "12607",
  "name": "love",
  "host": "loveyou",
  "status": "0",
  "groups": [
    {
      "groupid": "47",
      "name": "Flower"
    },
    {
      "groupid": "145",
      "name": "Sun"
    }
  ],
  "triggers": [
    {
      "triggerid": "211498",
      "description": "The host is unavailable by ICMP",
      "status": "0"
    },
    {
      "triggerid": "211499",
      "description": "CPU load above {$CPU}% ({ITEM.LASTVALUE})",
      "status": "0"
    },
    {
      "triggerid": "211500",
      "description": "The host has just been restarted (SysUptime {ITEM.LASTVALUE})",
      "status": "0"
    },
    {
      "triggerid": "211501",
      "description": "Sem resposta SNMP. Community {$SNMP_COMMUNITY}",
      "status": "0"
    },
    {
      "triggerid": "211574",
      "description": "Memory Usage is over {$MEM}% ({ITEM.LASTVALUE})",
      "status": "0"
    },
    {
      "triggerid": "211575",
      "description": "Free disk space is less than {$DISK}% on volume C:\\\\ Label:  Serial Number 1ab4e15c ({ITEM.LASTVALUE})",
      "status": "0"
    },
    {
      "triggerid": "211576",
      "description": "Free disk space is less than {$DISK}% on volume E:\\\\ Label:NETAPP_LUN_01  Serial Number 84048285 ({ITEM.LASTVALUE})",
      "status": "0"
    },
    {
      "triggerid": "211577",
      "description": "Free disk space is less than {$DISK}% on volume F:\\\\ Label:NETAPP_LUN_02  Serial Number 6426fd9 ({ITEM.LASTVALUE})",
      "status": "0"
    },
    {
      "triggerid": "211578",
      "description": "Free disk space is less than {$DISK}% on volume G:\\\\ Label:NETAPP_LUN_03  Serial Number 184b60f9 ({ITEM.LASTVALUE})",
      "status": "0"
    },
    {
      "triggerid": "211579",
      "description": "Free disk space is less than {$DISK}% on volume H:\\\\ Label:NETAPP_LUN_04  Serial Number 88541457 ({ITEM.LASTVALUE})",
      "status": "0"
    },
    {
      "triggerid": "211580",
      "description": "Free disk space is less than {$DISK}% on volume I:\\\\ Label:NETAPP_LUN_07  Serial Number f23669bc ({ITEM.LASTVALUE})",
      "status": "0"
    }
  ],
  "interfaces": [
    {
      "interfaceid": "2394",
      "ip": "192.168.1.190"
    },
    {
      "interfaceid": "2399",
      "ip": "192.168.1.190"
    }
  ]
}

Ich hätte gerne eine CSV-Datei in diesem Format:

NAME, GROUP, IP,           DESCRIPTION
love, Sun, 192.168.1.190, The host is unavailable by ICMP
love, Sun, 192.168.1.190 , CPU load above {$CPU}% ({ITEM.LASTVALUE})
love, Sun, 192.168.1.190 , The host has just been restarted

Ist dies möglich, wenn nur jq verwendet wird?

Ich habe zusammen mit jq den sed-Befehl verwendet:

CLIENTE=`echo "$RESULT" | jq -r .result[].groups[].name | sort | grep -m1 Cliente`
VISIBLENAME=`echo "$RESULT" | jq -r .result[].name | sed 's/ //g'`
HOST=`echo "$RESULT" | jq -r .result[].host | sed 's/ /_/g'`
IP=`echo "$RESULT" | jq -r .result[].interfaces[0].ip`
TRIGGERS=`echo "$RESULT" | jq -r .result[].triggers[].description | sed 's/ /_/g'`
TRIGSTATUS=`echo "$RESULT" | jq -r .result[].triggers[].status | sed 's/0/enabled/g;s/1/disabled/g'`
PRIORITY=`echo "$RESULT" | jq -r .result[].triggers[].priority | sed 's/0/notclassified/g;s/1/information/g;s/2/warning/g;s/3/average/g;s/4/high/g;s/5/disaster/g'`
ACTIVEHOST=`echo "$RESULT" | jq -r .result[].status | sed 's/0/monitored/g;s/1/unmonitored/g'`
TSTATUS=`paste <(echo "$TRIGGERS") <(echo "$TRIGSTATUS") <(echo "$PRIORITY")| sed 's/[[:space:]]/;/g'

echo "$CLIENTE;$VISIBLENAME;$HOST;$IP;$j;$ACTIVEHOST";

Ja, tatsächlich ist esEinfacherum es nur in JQ zu tun. Sie müssen die gewünschte Zeile als Array mithilfe von JQ-Filtern erstellen und dann den @csvFilter verwenden, um die Zeile im CSV-Format auszugeben (zusammen -rdamit die CSV nicht zusätzlich mit JSON maskiert wird).

Mir ist nicht ganz klar, was Ihre Anforderungen sind, da Ihr Code nicht wirklich mit der Ausgabe Ihres Beispiels übereinstimmt und nicht klar ist, was mit den wiederholten/verschachtelten Daten zu tun ist, aber hier ist ein teilweise funktionierendes Beispiel:

jq -r '.result[] | . as $result 
  | .triggers[] 
  | [$result.name, $result.groups[0].name, $result.interfaces[0].ip, .description] 
  | @csv'

was, unter Berücksichtigung Ihrer Testdaten, ausgibt

"love","Flower","192.168.1.190","The host is unavailable by ICMP"
"love","Flower","192.168.1.190","CPU load above {$CPU}% ({ITEM.LASTVALUE})"
"love","Flower","192.168.1.190","The host has just been restarted (SysUptime {ITEM.LASTVALUE})"
"love","Flower","192.168.1.190","Sem resposta SNMP. Community {$SNMP_COMMUNITY}"
"love","Flower","192.168.1.190","Memory Usage is over {$MEM}% ({ITEM.LASTVALUE})"
"love","Flower","192.168.1.190","Free disk space is less than {$DISK}% on volume C:\\ Label:  Serial Number 1ab4e15c ({ITEM.LASTVALUE})"
"love","Flower","192.168.1.190","Free disk space is less than {$DISK}% on volume E:\\ Label:NETAPP_LUN_01  Serial Number 84048285 ({ITEM.LASTVALUE})"
"love","Flower","192.168.1.190","Free disk space is less than {$DISK}% on volume F:\\ Label:NETAPP_LUN_02  Serial Number 6426fd9 ({ITEM.LASTVALUE})"
"love","Flower","192.168.1.190","Free disk space is less than {$DISK}% on volume G:\\ Label:NETAPP_LUN_03  Serial Number 184b60f9 ({ITEM.LASTVALUE})"
"love","Flower","192.168.1.190","Free disk space is less than {$DISK}% on volume H:\\ Label:NETAPP_LUN_04  Serial Number 88541457 ({ITEM.LASTVALUE})"
"love","Flower","192.168.1.190","Free disk space is less than {$DISK}% on volume I:\\ Label:NETAPP_LUN_07  Serial Number f23669bc ({ITEM.LASTVALUE})"

Die Zitate sind mehr als Sie verlangt haben, aber es handelt sich um eine völlig gültige CSV-Datei.
