Hi All: Context: NFSv3: I would like to get your input on the following NFS stats recorded on our server. I have read up this thread(http://www.opensubscriber.com/message/nfs@xxxxxxxxxxxxxxxxxxxxx/7833588.html) describing the contents of /proc/net/rpc/nfsd; My Numbers are really high, for 'th' line in nfsd file: I am not able to ascertain as to: My server is heavily busy or poorly performing, because each thread is busy that big number of times on the 'th' line; Q0. Does the stats below represent a bad performance? Q1. Is there anymore way I can tweak this if this represents a bad performance? You input is greatly appreciated and will help us tweak this server and better understand the performance. Thank you, Amit /******************/ Generally on all of My Client this is what the nfsstats reports: retans number fluctuates but not greatly. To me retrans number seems negligible. # nfsstat Client rpc stats: calls retrans authrefrsh 138601858 13119 0 # uname -a Linux nfs3-io-0-3.local 2.6.18-53.1.14.el5 #1 SMP Wed Mar 5 11:37:38 EST 2008 x86_64 x86_64 x86_64 GNU/Linux NFS server:# cat /proc/net/rpc/nfsd rc 579356 2561581103 930328921 fh 68593119 0 0 0 0 io 3005241904 1001209956 th 128 43577408 757955.761 677495.276 387088.572 462962.421 425292.746 165116.697 66147.746 26071.602 8148.127 9079.092 ra 256 319824137 968005 35905 6510 2981 1790 1450 1056 895 634 141481 net 3493483810 0 3492990059 29031 rpc 3489730527 0 0 0 0 proc2 18 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 proc3 22 116 11578551 9138195 364276603 91767377 380 318502944 2552319828 174234 11301 1470 0 178776 6302 15842 2962 1001562 335879 122371298 117 0 18968257 proc4 2 0 0 proc4ops 40 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 NFS server:# nfsstat Server rpc stats: calls badcalls badauth badclnt xdrcall -803696698 0 0 0 0 Server nfs v3: null getattr setattr lookup access readlink 116 0% 11579177 0% 9138217 0% 364330037 10% 91788465 2% 380 0% read write create mkdir symlink mknod 319793180 9% -1742476768 73% 174245 0% 11301 0% 1470 0% 0 0% remove rmdir rename link readdir readdirplus 178780 0% 6302 0% 15842 0% 2962 0% 1001733 0% 335887 0% fsstat fsinfo pathconf commit 122372898 3% 117 0% 0 0% 18968795 0% NFS server:# ifconfig -i eth0 eth0 Link encap:Ethernet HWaddr xx:xx:xx:70:AD:27 inet addr:xx.xx.24.251 Bcast:xxx.xx.24.255 Mask:255.255.255.0 inet6 addr: xxxx::xxx:9ff:fe70:ad27/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:180118110167 errors:0 dropped:4 overruns:0 frame:0 TX packets:238857904405 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:74126472507659 (67.4 TiB) TX bytes:306386976112971 (278.6 TiB) Interrupt:169 Memory:f8000000-f8012100 /******************/ -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
