Server administration issue

sc flag

How can you troubleshoot a slow server response time? My server performance is deteriorating so fastly. I've tried fixing server software and configurations. Also checked with network connectivity. It seems there is no issue. Could you please help me?

What server? How do you measure performance? How is it configured? As it stands it is too general to get relevant answers.

Check CPU: top or htop

Check proceses: ps -auxf

Memory: free -m

Iops: iotop -oPa

Install nmon and nload

Check IO/Wait: iostat -m 2 and iostat -xm 2

Tuning filesystem (noatime)

Tuning sysctl.conf

Uses: Apachebuddy

Uses: MySQLTunner

Tuning PHP

strace

lsof -p

vmstat

stat

Check hardrive: smartmontools

Check: sudo hdparm -I /dev/sda and sudo hdparm -tT /dev/sda and sudo hdparm -I /dev/sda | grep -i speed

And BIOS/UEFI configuration... Uses Dell Server? Memory Operation Mode? Snoop Mode? Supermicro? Gigabyte? Quanta Server?

Network velocity in Gigabps?

Check disk velocity: dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync

RAID Monitoring?

cat /proc/mdstat

cat /proc/mdstat

mdadm -D /dev/md1

mdadm -D /dev/md0

MAILADDR [email protected]

./mdadm --monitor --mail=root@localhost --syslog --delay=300 /dev/md0 --daemonise

in gernally not a bad answer, but it needs supporting information, specially for the tuning part and a hint that it could break things or even in more worse conditions destroy

Have you tried to add it to monitoring system like 'zabbix 'to get overviwe of it's performance ? Check CPU, Memory, Iops, Netowrk Traffic. Each one of those matrices can make your server slower.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
