This question is good for the user list, but if you can't send mail to dev lost you're probably using HTML email or something. vger.kernel.org has some pretty strict anti-spam policies.

Hi all,
i have been trying to send this to the dev mailing list, but the mail was rejected! for what ever reason, though i am subscribed. any one facing this issue with the dev list? i thought it is related to the dev the most since i was digging inside the code for a wile now.
never the less, I have noticed if there are some clients misbehaving it will effect the whole cluster, causing blocked requests and slowing down every thing. particularly when a client is having a network related issue, like a congested network or a faulty optic. so i am trying to track the clients on our cluster. any good method of locating/listing all the currently connected clients?
and, i am trying to find the clients from there requests, i have been through the source code for the past couple of days but could not find what i wanted. the dump operations, e.g. from running (ceph daemon osd.xxx dump_historic_ops), gives me something like: (running ceph v0.94.2)
"description": "osd_op(client.36076101.0:62833746 default.36046497.2__shadow_2092280179.2~MFtK8tZp8-UmvkM0qbVkf6B4xQbLT-p.50_1 [] 108.f7ba6ce0 ack+ondisk+write+known_if_redirected e331887)",
"initiated_at": "2015-12-05 15:26:08.159832",

"duration": 1.256738,
"type_data": [
"commit sent; apply or cleanup",
{
"client": "client.36076101",
"tid": 62833746
},
.
.
.
.
{
"time": "2015-12-05 15:26:09.416570",
"event": "done"
}
]
]
},
the only peace of info that it might be useful (i assumed) is the description, i can see the client id in it (client.36076101.0:62833746, it is the client id, right?) but could not understand from where it comes. my head was spinning inside the source, though its the first time i go there ;). first i thought it is related to the client ip or something, but could not confirm that. any one have a clue whether this can get me somewhere? any other ideas are appreciated.
thanks
Ali
