An earthworm 64bit 7.8 routine for reading tracebuf2 data from a ring and saving to a mongodb capped colleciton that acts as a ring. This ring can then be used to created archived collections. See https://github.com/pnsn/quickshake

ring2mongo only writes trace data to mongodb. It is not concerned with serving the data.

Trace Data are written to a single collection and indexed on key (SCNL) and starttime. It is recommended that you create a capped collection to keep the colllection from growing too large.

1. DB name: waveform
2. Collection: ring

To set up mongo do the folllowing:

• > use waveforms
• > db.createCollection( "ring", { capped: true, size: SOME_SIZE_IN_BYTES } )
• > db.cwaves.createIndex({"key": 1, "starttime": 1})

Use as a docker routine for local testing and configuration. Docker has not been tested for production

./ew_containerize This script will do the following:

• Mount the current $dir/params to the ew params dir, which will put your local files into the ew params directory.
• Start an interactive shell and put you in the mounted params dir

Next run the startstop script in the params dir startstop.sh

Add any configure files from /eworm/earthworm_[version]/params to /eworm/run/params

Using startstop as an entrypoint does not work since the child processes don't run.

Follow the directions to install Mongo-C Driver https://github.com/mongodb/mongo-c-driver I found that building from source was the only way to get it to work on Centos7 You'll probably have to edit the following Env variables. These paths are RHEL/CENTOS 6.5 & 7

• echo "export CPATH=$CPATH:/usr/local/include/libmongoc-1.0:/usr/local/include/libbson-1.0" >> ~/.bashrc

• export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig" >> ~/.bashrc
• source ~/.bashrc *Ensure openssl and openssl-devel are installed before you run ./configure to set the SSL compile flag to true.
