Vaisala RVP900

Appendix E _____________________________________________________ Time Series Recording
VAISALA______________________________________________________________________ 427
Each of the scripts contain extensive comments and should be edited
depending on your configuration. The scripts are shipped configured for
the RVP900 end, so you need to edit the archive host’s files. You also need
to edit all tsexport files to explicitly set the target IP address to which it will
broadcast the time series. Vaisala recommends that you use a single target
host. A broadcast address can be used, but be careful that all recipients can
handle the traffic, and that there are no 10baseT network sections.
E.3.3 Configuring Automatic Startup of
tsimport and tsexport
As root, enter the following commands:
#chkconfig --add tsimport
#chkconfig --add tsexport
Once configured with the chkconfig command, you can start and stop these
programs with the commands:
#service tsimport start
#service tsimport stop
E.3.4 Configuring Network Buffering for
tsimport
For tsimport to successfully read all the pulses of data from the network,
the network read buffers must be enlarged. Do this by editing the
/etc/sysctl.conf file and adding these commands to the end:
net.core.rmem_default = 1000000
net.core.rmem_max = 4000000
Reboot for this to take effect.
