SQL 查詢zabbix數據庫

1.導出被監控主機CPU使用率數據

select f.ip,b.*,ROUND(avg(t.value_avg),2) 'avg_value' from 
trends t,interface f,
(
select a.name as 'groupname',h.host,i.hostid,i.itemid,i.key_ from items i,
(
SELECT
    g.groupid  'groupid',
    g.NAME 'name',
    hg.hostid 'hostid'
FROM
    groups g,hosts_groups hg
WHERE
  g.groupid=hg.groupid
) a,hosts h
where 
    i.hostid=a.hostid
and 
    h.hostid=a.hostid
) b
where 
  t.itemid = b.itemid
and
  f.hostid = b.hostid
and
  b.groupname = 'Hostgroup_name'
and 
  b.key_  ='system.cpu.util[,system]' 
and
  t.clock > UNIX_TIMESTAMP('2017-11-01 00:00:00')
and
  t.clock < UNIX_TIMESTAMP('2017-11-30 00:00:00')
group by t.itemid order by avg_value desc;

2.導出告警事件

SELECT
    e.eventid '事件ID',
    ( SELECT ( SELECT NAME FROM groups WHERE groupid = hg.groupid ) FROM hosts_groups hg WHERE hostid = h.hostid LIMIT 1 ) '分組',
    h.HOST '主機',
    REPLACE ( t.description, '{HOST.NAME}', h.HOST ) '告警內容',
    FROM_UNIXTIME( e.clock ) '時間',
CASE
    t.priority 
    WHEN 0 THEN
    "not classified" 
    WHEN 1 THEN
    "information" 
    WHEN 2 THEN
    "warning" 
    WHEN 3 THEN
    "average" 
    WHEN 4 THEN
    "high" 
    WHEN 5 THEN
    "disaster" 
    END AS "事件級別",
CASE
    e.
VALUE
    
    WHEN 1 THEN
    "problem" 
    WHEN 0 THEN
    "OK" 
    END AS "狀態" 
FROM
    events e,
    functions f,
    items i,
    hosts h,
    triggers t 
WHERE
    e.objectid = f.triggerid 
    AND f.itemid = i.itemid 
    AND t.triggerid = f.triggerid 
    AND f.itemid = i.itemid 
    AND i.hostid = h.hostid 
    AND e.object = 0 
    AND e.source = 0 
    AND e.clock > UNIX_TIMESTAMP( '2018-12-01 00:00:00' ) 
    AND e.clock < UNIX_TIMESTAMP( '2019-01-14 00:00:00' ) 
ORDER BY
eventid DESC

3.導出網絡接口流量趨勢數據

select FROM_UNIXTIME(clock,'%Y年%m月%d日') date,t.value_max 'max_transmit',t.value_avg 'avg_transmit',
      t.value_min 'min_transmit' from trends_uint t, 
      (select i.itemid from items i,(select h.hostid from 
      hosts h where h.name="FG1000D")b where b.hostid=i.hostid 
      and i.status = 0 and 
      i.name = 'Outgoing traffic on interface WAN-1514') oh 
      where t.itemid = oh.itemid  and  t.clock > UNIX_TIMESTAMP("2018-09-01 00:00:00") 
      and  t.clock < UNIX_TIMESTAMP("2018-10-01 00:00:00") 
      group by from_unixTime(clock,'%Y-%m-%d')
