Subject: wrong latency info for flexfiles on layout return
Date: Tue, 6 Feb 2018 23:10:19 +0100 (CET) [thread overview]
Message-ID: <1253710805.3166627.1517955019275.JavaMail.zimbra@desy.de> (raw)
Hi Trond et al.
by exploring data provided on layoutreturn I can see that some
information is wrong, in particular the IO latency completition
time for write:
{
"iostats":[
{
"deviceAddr":"tcp://192.168.178.40.128.2",
"duration":{
"seconds":5,
"nseconds":285924462
},
"readInfo":{
"bytes":0,
"latency":{
"completitionTime":{
"seconds":0,
"nseconds":0
},
"bytesRequested":0,
"opsCompleted":0,
"busyTime":{
"seconds":0,
"nseconds":0
},
"opsRequested":0,
"bytesCompleted":0,
"bytesNotDelivered":0
},
"count":0
},
"fh":"01caffee00000000b1f9635e000d00000800000000000000050130",
"writeInfo":{
"bytes":624193536,
"latency":{
"completitionTime":{
"seconds":25737,
"nseconds":816217921
},
"bytesRequested":624193536,
"opsCompleted":9526,
"busyTime":{
"seconds":5,
"nseconds":224017937
},
"opsRequested":9526,
"bytesCompleted":624193536,
"bytesNotDelivered":0
},
"count":9526
},
"deviceId":"00000001000000000000000000000000",
"open-stateid":"5a7a259b0000000100000004"
}
]
}
you can see this with wireshark as well.
Regards,
Tigran.
