Issue/Introduction

Summary: 

 

CA SystemEDGE has the ability to monitor NFS file systems which are present on Unix based platforms.   This article will explain what file systems CA SystemEDGE detects as NFS and how monitoring of NFS file systems can be disabled.

 

Instructions

 

1.  SystemEDGE populates device table (devTable1.3.6.1.4.1.546.1.1.1.7.1) with all file systems mounted to the system.   This will include nfs file systems.  

 

2.  SystemEDGE will be consistent with the output from the following OS commands

df -h

mount

3.  SystemEDGE has a parameter called no_stat_nfs_filesystems.   When this is enabled SystemEDGE will populate the nfs file systems within the device table (devTable1.3.6.1.4.1.546.1.1.1.7.1) with values of 0.   SystemEDGE will not actively stat these file systems for current values.

 

4. The only values SystemEDGE will consider as "NFS" are the following (All other files types will not be excluded using the no_stat_nfs_filesystems parameter):

 

NFS

SFS

NFS3

AUTOFS 

 

 5.  You can verify what disks show up as nfs by polling DevType (1.3.6.1.4.1.546.1.1.1.7.1.10):

<14> <1.3.6.1.4.1.546.1.1.1.7.1.10.1> <OctetString> <ext4>

<14> <1.3.6.1.4.1.546.1.1.1.7.1.10.3> <OctetString> <ext4>

<14> <1.3.6.1.4.1.546.1.1.1.7.1.10.6> <OctetString> <ext4>

<14> <1.3.6.1.4.1.546.1.1.1.7.1.10.54> <OctetString> <tmpfs>

<14> <1.3.6.1.4.1.546.1.1.1.7.1.10.57> <OctetString> <nfs>

<14> <1.3.6.1.4.1.546.1.1.1.7.1.10.58> <OctetString> <nfs>

6.  You can then use DevMntPt (1.3.6.1.4.1.546.1.1.1.7.1.3) to correlate the file system to the DevType.

 <14> <1.3.6.1.4.1.546.1.1.1.7.1.3.1> <OctetString> </>

<14> <1.3.6.1.4.1.546.1.1.1.7.1.3.3> <OctetString> </boot>

<14> <1.3.6.1.4.1.546.1.1.1.7.1.3.6> <OctetString> </home>

<14> <1.3.6.1.4.1.546.1.1.1.7.1.3.54> <OctetString> </dev/shm>

<14> <1.3.6.1.4.1.546.1.1.1.7.1.3.57> <OctetString> </export/storeaudit>

<14> <1.3.6.1.4.1.546.1.1.1.7.1.3.58> <OctetString> </net/corpnas1/export/export>
