| Hi, I was wondering if it's possible for MQ channels (set up on iSeries platform) to be monitored, so in the event that a channel (mainly sender or receiver) is, for example, not running that an e-mail notification can be sent to me to alert me of such. Does anyone monitor their channels? If it can be done via i Navigator, that ca work. |

When a channel end it will write a Channel Event message if you wish. This is a PCF Event message. You can have a program monitoring the event queue which can do anything you wish. There are a number of Administration utitlities around which can do this but the base MQ product itself will not to this. However, 'yes' with a monitoring product it is possible, without too much effort, to get them to email you (or whatever),
Cheers,
Paul.

It is common for channels not to be running. If XMITQs are configured correctly, the sender channel will auto start when msgs land on the XMITQ. If your qm.ini CHANNELS stanzas are correct, the receiver should start when the sender tries to connect to it.
Your inquiry would lead me to believe you have a situation where a channel stops and does not start when it has msgs to send. Is that the case? |

Channels in "retry" or "binding" state - generally need attention (and monitoring).
Other states are normal. However you should test your xmit queue triggering.
If you want a channel to run all the time, you can set the DISCINT accordingly.
As for monitoring there any many possible solutions. You can code your own in your favourite language to use PCF or examine MQSC output for the channel status at intervals. Most monitoring products also work using PCF.
Receiving channel event messages is also possible in your own code or there are tools can that do this for you (such as MO71).
When such code or tools detect an issue, they could generate an Email or pass an alert via SNMP or whatever.
IBM have published a web based monitoring example tool recently
http://www.ibm.com/developerworks/websphere/library/techarticles/1311_jin/1311_jin.html
This is an open source tool, that could be extended to send mails
http://www.capitalware.com/mqcm_overview.html
A fairly powerful tool (free to use) is Qflex - this does offer Email alerts
http://netflexity.com/get-qflex-4/
Monitoring tools don't have to run on the same platform as the QM, as they can connect using MQ client.
Probably the simplest case would be a shell script running MQSC commands at intervals (or run via cron).

On the i, we do not have any issues with receiver channels not starting when msgs are put on them. I just want to monitor for the sender channels in particular, so in case it is down for whatever reason, I will get notified. Issues have arisen in the past but was on the remote system, so I just want to play it safe.
Thanks for the links, but can the Qflex be used to connect to an iSeries? |

Status of the sender channel will inevitably tell you about the sender-receiver channel at both ends. If the receiver end goes dead, the sender end will do so shortly.
