Hi Bob,

>LSU's IDD ingestor Sirocco has shown signs of instability as of late. 
>The LSU downstream feeders have already moved to Seistan, I believe now

Sounds reasonable.

>Currently 
>Sirocco is feeding from Datoo.srcc.lsu.edu, Thelma.ucar.edu, and 
>Unidata2.ssec.wisc.edu with the following request configuration:
>#
>request         NEXRAD|IDS|UNIDATA|HRS|WSI|WMO|DDS|HDS|FNEXRAD|NPORT ".*"    
>datoo.srcc.lsu.edu
>request         DIFAX|FSL2|MCIDAS  ".*"    thelma.ucar.edu 
>request         IDS|DDPLUS  ".*" unidata2.ssec.wisc.edu 
>request         HRS         ".*" unidata2.ssec.wisc.edu 
>request         UNIWISC     ".*" unidata2.ssec.wisc.edu 
>request         NNEXRAD     ".*" unidata2.ssec.wisc.edu 
>request         NMC3        ".*" datoo.srcc.lsu.edu


>Seistan's request configuration would change to:


># IDS|DDPLUS - world observational data from NOAAPORT
>#
>request IDS|DDPLUS      ".*"    datoo.srcc.lsu.edu      PRIMARY
>request IDS|DDPLUS      ".*"    unidata2.srcc.lsu.edu   ALTERNATE
>#request IDS|DDPLUS      ".*"    sirocco.srcc.lsu.edu    ALTERNATE

This looks good.  If sirocco is going away for good, you should
remove the request line to it in order to keep seistan's ldmd.conf
file readable.

>#
># HDS - model output from NOAAPORT
>#
>request HDS     ".*"    datoo.srcc.lsu.edu      PRIMARY
>request HDS     ".*"    thelma.ucar.edu         ALTERNATE
>#request        HDS     ".*"    sirocco.srcc.lsu.edu    ALTERNATE

Please change thelma.ucar.edu to atm.geo.nsf.gov.  This is part of
the reorganization of the IDD.  Ditto the comment about removing
the request to sirocco.

>#
># NNEXRAD    - NEXRAD Level III products from NOAAPORT
>#
>request NNEXRAD ".*"    datoo.srcc.lsu.edu      PRIMARY
>request NNEXRAD ".*"    unidata2.srcc.lsu.edu   ALTERNATE
>#request        NNEXRAD ".*"    sirocco.srcc.lsu.edu    ALTERNATE

This looks good.  Ditto the comment about removing the request to
sirocco.

>#request        FNEXRAD|UNIWISC ".*"    sirocco.srcc.lsu.edu    PRIMARY

Ditto the comment about removing the request to sirocco.

Please add:

request FNEXRAD|UNIWISC ".*"    atm.geo.nsf.gov    ALTERNATE

># DIFAX - DIFAX-like products created at University of Wisconsin/AOS

>#request        DIFAX|FSL2      ".*"    sirocco.srcc.lsu.edu    PRIMARY

Please change thelma.ucar.edu to atm.geo.nsf.gov.  This is part of the
reorganization of the IDD.  Ditto the comment about removing the
request to sirocco.

This list should be changed.  Here are some comments:

- NMC3 is FNEXRAD.

  Unless datoo is requesting FNEXRAD or WSI from an upstream
  machine -- and it should not be --, having these requests will simply
  result in more rpc.ldmds running, but they won't be doing anything
  but using process IDs and CPU time.

- WMO is the combination of IDS|DDPLUS|HDS; DDPLUS is the combination
  of DDS|PPS.  Given this, the requests for HRS, DDS and WMO overlap.
  Not only that, you already have all feeds in WMO covered by the
  two requests in the IDS|DDPLUS and HDS sections above.

- NPORT is not used

Given these last items, _all_ of the above requests should be dumped.

>I believe the current settings on Thelma and Unidata2.ssec.wisc.edu 
>will allow Seistan to feed.

Thelma is not setup to feed LSU, but atm is.

>This being the case, the plan is to direct 
>Seistan to feed directly off of Thelma and  unidata2.ssec.wisc.edu 
>taking Sirocco out of the loop.

It should feed off of datoo, unidata2, and atm.

>After a short proving period I will then 
>direct Sirocco to feed from Seistan locally.

OK.
