南大通用GBase 8a通过python获得指定表的所有event信息

GBase 8a 默认能获得所有的故障event信息，当event比较多时，需要人工将信息进行筛选。本文通过pyton调用gcware库获得指定表的所有event信息。

参考

GBase 8a查看某张表当前主副本可用状态、是否存在event

脚本程序

[gbase@rh6-1 zxq]$ cat getEventByTablename.py
#!/usr/bin/env python

import sys
if len(sys.argv)!=3:
  print('Usage: dbname table')
  exit(1)
import gcware

tablename=sys.argv[1]+'.'+sys.argv[2]
print 'check',tablename,' ...'
print '-----dmlevent---------'
all=gcware.getdmlfevents()
for o in all:
  if o['tablename']==tablename:
    print('eventid=%s' %(o['eventid']))
    print('tabletype=%s' %(o['tabletype']))
    for n in o['dmldatacopyids']:
      print 'nodeipaddr='+n['nodeipaddr']
      print 'segname='+n['segname']
    print
print '-----ddlevent---------'
all=gcware.getddlfevents()
for o in all:
  if o['tablename']==tablename:
    print('eventid=%s' %(o['eventid']))
    print('tabletype=%s' %(o['tabletype']))
#    print('datacopyids=',o['datacopyids'])
    for n in o['datacopyids']:
      print 'nodeipaddr='+n['nodeipaddr']
      print 'segname='+n['segname']


print '-----dmlstorageevent---------'
all=gcware.getdmlstoragefevents()
for o in all:
  if o['tablename']==tablename:
    print('eventid=%s' %(o['eventid']))
    print('tabletype=%s' %(o['tabletype']))
    n=o['datacopyid']
    print 'nodeipaddr='+n['nodeipaddr']
    print 'segname='+n['segname']
    print
