|NFSLOG.CONF(4)||File Formats and Configurations||NFSLOG.CONF(4)|
The nfslog.conf file specifies the location of the NFS server logs, as well as the location of the private work files used by the NFS server and nfslogd(1M) daemon during logging. Each entry in the file consists of a mandatory tag identifier and one or more parameter identifiers. The parameter identifier specifies the value or location of the specific parameter. For instance, the parameter identifier "log=/var/nfs/logs/serverLog" specifies the location of the NFS server activity log. The mandatory tag identifier serves as an index into the /etc/nfs/nfslog.conf file to identify the various parameters to be used. At export time, the share_nfs(1M) command specifies the NFS server logging parameters to use by associating a tag from the /etc/nfs/nfslog.conf file to the exported file system. It is legal for more than one file system to be exported using the same logging tag identifier.
NFS server logging is not supported on Solaris machines that are using NFS Version 4.
A "global" tag identifier is included in /etc/nfs/nfslog.conf. It specifies the default set of values to be used during logging. If no tag identifier is specified at export time, then the values in the "global" entry are used. The "global" values can be modified by updating this entry in /etc/nfs/nfslog.conf.
Each entry in the file must contain a mandatory tag identifier and at least one parameter/value pair. If a parameter is not specified in a given entry, the global value of the parameter will be used. The exact entry syntax follows:
<tag> [defaultdir=<path>] [log=<path><file>] \ [fhtable=<path><file>] [buffer=<path><file>] [logformat=basic|extended]
The "global" tag may be modified so that all exported file systems that enabled logging use a common set of parameters that conform to the specific needs of the user. These values are used until a specific tag identifier overrides them.
global defaultdir=/var/nfs log=logs/nfslog \ fhtable=tables/fhtable buffer=buffers/nfslog_workbuffer \ logformat=basic
Example 2 Overriding the Global defaultdir and logformat
Because log files can become very large, it may be desirable to store the logs and working files in separate file systems. This can be easily accomplished by simply specifying a different defaultdir for every file system exported by means of a unique tag:
engineering defaultdir=/engineering/logging \ logformat=extended accounting defaultdir=/accounting/logging marketing defaultdir=/marketing/logging
File systems shared with the engineering identifier will have their logs and workfiles located in /engineering/logging. For instance, the log file will be located at /engineering/logging/logs/nfslog. Note that the engineering log file will be stored in the extended format, while the rest of the log files will remain in the basic format.
Any of the parameters can be updated in a tag identifier, which overrides the global settings.
Logs, work files, and file handle to path mapping database can become very large. Be aware of appropriate placement within the file system name space. See nfslogd(1M)) for information on pruning the database files and cycling logs.
