首先运行下面的脚本(脚本摘自:http://www.th7.cn/system/lin/201304/38800.shtml) #!/bin/bashfor i in /usr/share/mibs/ietf/IPSEC-SPD-MIB /usr/share/mibs/ietf/IPATM-IPMC-MIB \/usr/share/mibs/iana/IANA-IPPM-METRICS-REGISTRY-MIB /usr/share/mibs/ietf/SNMPv2-PDUdo mv $i
一.查看sql语句是否发生死锁 1.查看数据库的进程.SELECT * FROM pg_stat_activity WHERE datname='死锁的数据库ID ';检索出来的字段中,[wating ]字段,数据为t的那条,就是死锁的进程,找到对应的[procpid ]列的值. 例如:SELECT procpid FROM pg_stat_activity WHERE datname='数据库ID' and waiting ='t'; 2.杀掉进程. kill有两种方式,第一种是:SELE
SELECT table_name, pg_size_pretty(table_size) AS table_size, pg_size_pretty(indexes_size) AS indexes_size, pg_size_pretty(total_size) AS total_size FROM ( SELECT table_name, pg_table_size(table_name) AS table_size, pg_indexes_size(table_name) AS inde
1. 查看当前数据库大小以及记录行数 select trim(pgdb.datname) as database, sum(b.mbytes) as mbytes, sum(a.rows) as rows from (select db_id, id, name, sum(rows) as rows from stv_tbl_perm a group by db_id, id, name) as a join pg_class as pgc on pgc.oid = a.id join pg_n
1. 查看当前库sehcma大小,并按schema排序 SELECT schema_name, pg_size_pretty(sum(table_size)::bigint) as "disk space", ( as "percent" FROM ( SELECT pg_catalog.pg_namespace.nspname as schema_name, pg_relation_size(pg_catalog.pg_class.oid) as table_si
zabbix 3.4 监控报错No Such Instance currently exists at this OID 1.首先查看监控的路由器的监控项是否报警 监控主机报错出现这个 No Such Instance currently exists at this OID 2.在zabbix服务器测试一下是否联通. snmpwalk -v 2c -c private 192.168.1.1 1.解决办法就是: 清除所有监控项以及模块 Template Net Network Generic
在psql中,我们可以通过一系列的的快捷命令查看数据库元素,如:\d 查看当前搜索路径下的表,那么内部用到的SQL语句是什么呢,可以通过命令来设置是否打印出来: apple=# \set ECHO_HIDDEN on apple=# \c mydb You are now connected to database "mydb" as user "apple". mydb=# \d ********* QUERY ********** SELECT n.nspnam
