All LDAD processes log their activity for both system monitoring and debugging. Listed below are the LDAD log files, their respective nodes and locations, and a brief description.
Except as noted, all of these files are written to /data/logs/<user>/<yyyymmdd>/ on the indicated node.
| Name | Host:User | Description |
|---|---|---|
| CO_serv<pid><hostname><timestamp> | ls1:ldad | communication process log: logs socket activity |
| hmingestd-ls1-<timestamp> | ls1:ldad | ingest-for-dissemination log |
| listener<pid><hostname><timestamp> | ds1:ldad | logs rcp and remsh activity by the listener |
| newLDADdataNotification<pid><hostname><timestamp> | ls1:ldad | logs sending of data from ls1 to ds1 |
| pollForData<pid><hostname><timestamp> | ds1:ldad | log of sending products to ls1 for use by dissemination system |
| ROSA_Acq<pid><hostname><timestamp> | ls1:ldad | ROSA acquisition log |
| textdbNotify00000<hostname>000000 | ds1:fxa | triggers log - files notified for dissemination |
| dtmf<Month><day> | ls1:ldad | (this file is in /data/logs/ldad) logs activity on the DTMF input channel |
LDAD decoding and storage occurs on ds1. The logs below are found in ds1:/data/logs/ldad/<yyyymmdd>.
| Name | Description |
|---|---|
| CommsRouter<pid><hostname><timestamp> | lists each LDAD dataset as its notification passes through the system |
| DataController<pid><hostname><timestamp> | essentially similar to CommsRouter log |
| routerLdadDecoder<pid><hostname><timestamp> | logs decoding of files from CSV format - files are read from $FXA_DATA/LDAD/Raw and written to $FXA_DATA/LDAD/decoded |
| routerStoreNetcdf<pid><hostname><timestamp> | logs conversion of decoded files and storage in netCDF files |
| routerStoreText<pid><hostname><timestamp> | logs conversion of decoded files and storage in the text database |
| routerShefEncoder<pid><hostname><timestamp> | logs SHEF encoding of decoded files |
LDAD monitor processes run on as1 and ls1. These logs are found in /data/logs/<user>/<yyyymmdd>.
| Name | Host:User | Description |
|---|---|---|
| MakeLDApage<pid><hostname><timestamp> | ls1:ldad | one log each for acquisition and dissemination monitor page - the script is generally run in verbose mode |
| MakePROCpage<pid><hostname><timestamp> | as1:fxa ls1:ldad |
logs the status of each network connection and LDAD process |
| MakeSUMMpage<pid><hostname><timestamp> | as1:fxa | logs each run of the summary page |
| watchDogExternal<pid><hostname><timestamp> | ls1:ldad | logs each time it starts a process |
| watchDogInternal<pid><hostname><timestamp> | ds1:ldad | logs each time it starts a process
Both listener and pollForData seem to fail rather frequently; the watchDog restarts them. listener calls sendLDADnotification.pl; its output ends up in this log. |
Dissemination-related processes run on ls1.
| Directory | Name | Description |
|---|---|---|
| /data/logs/ldad/<yyyymmdd> | tmain<pid><hostname><timestamp> | logs BBS activity |
| /data/logs/ldad | faxmodem.<Month>.<day> | logs activity of the fax modem |
| /var/opt/hylafax/log | c0000* | fax session files - one per session
note that you must be root to view these |
Fax sessions are also noted in /var/adm/syslog.log.
The MAPS Surface Assimilation System runs on AS2. Logs are written to /data/logs/fxa/ldad/MSAS/logs. "out" files are a verbose log of the script, and are written to /data/logs/fxa/ldad/MSAS/output, while "err" files, written to /data/logs/fxa/ldad/MSAS/errors, are zero length in most cases.
