Issue::

After a two machine migration, warnings like the following are seen in the eHealth system log:

Warning Pgm nhiPoller[Net]: Error reading (possibly missing) MTF 'F:/eHealth/poller/mib2-enet-fd-nu-v2c-hs-IF-20.mtf', corresponding elements cannot be polled.

Environment:

6.3.x

Cause:

Missing mtf's

Resolution:

These warnings are regarding mtf's that are automatically created during discovery. To resolve this issue you can collect the mtf's from the old system in the $NH_HOME/poller directory, and then move them over to the new system and put them in the $NH_HOME/poller directory. Then cycle the eHealth server process with an nhServer stop / start.

As a final step run: $NH_HOME/bin/sys/nhiLoadMtfVars -fileName <mtfFile> to load the mtf's into the database. After performing these steps the warnings will no longer be seen.
