| 3 | If iSymphony is using excessive amounts of CPU time, or is affecting call quality on the system it's installed on, here are a few things to check before opening a ticket with us. | ||
| 4 | |||
| 5 | == Troubleshooting == | ||
| 6 | |||
| 7 | 1. Ensure that the hardware installed in the system running iSymphony is reasonably close to our [[Hardware Requirements>>doc:ISYMDOCS.iSymphony Requirements]]. It doesn't need to exactly meet the recommendations, due to the inherent variability in requirements, but it should be close. | ||
| 8 | 1. If you are using call detail records in MySQL, ensure that you have applied the [[index fix for the CDR database>>doc:Missing MySQL CDR Index]]. | ||
| 9 | |||
| 10 | == Further Support == | ||
| 11 | |||
| 12 | If you've checked the above items, and you're still having resource usage or call quality issues, feel free to open a ticket including the following information: | ||
| 13 | |||
| 14 | 1. The symptoms you're experiencing (e.g. high cpu usage, high network traffic, call quality issues, etc), including how frequently they happen. | ||
| 15 | 1. ((( | ||
| 16 | The output of the following commands: | ||
| 17 | |||
| 18 | {{code}} | ||
| 19 | $ cat /proc/cpuinfo | ||
| 20 | $ free -m | ||
| 21 | $ ps aux | grep -e "java.*isymphony3" | ||
| 22 | {{/code}} | ||
| 23 | ))) | ||
| 24 | 1. All files in /opt/isymphony3/server/log. | ||
| 25 | 1. All files in /opt/isymphony3/server/conf. | ||
| 26 | 1. Approximately how much call traffic does this phone system handle (calls per day, simultaneous calls, etc)? | ||
| 27 | 1. If you are using queues on this phone system, | ||
| 28 | 11. How many queues are running on the system (even if they aren't licensed in iSymphony)? | ||
| 29 | 11. How many agents are logging into queues at a time? | ||
| 30 | 11. What ring strategy are you using for your queues? | ||
| 31 | 1. If you can catch the system while it is lagging for additional information, include the following as well: | ||
| 32 | 11. A screenshot of the top command while the issue is occurring. | ||
| 33 | 11. ((( | ||
| 34 | The output of these commands: | ||
| 35 | |||
| 36 | {{code}} | ||
| 37 | $ netstat -lanp | grep 5038 | ||
| 38 | $ netstat -lanp | grep 50000 | ||
| 39 | $ cat /proc/`cat /opt/isymphony3/server/iSymphonyServer.pid`/stat | ||
