Command line tool to evaluate connectivity and object count consistency for DataONE member nodes.
This tool is run by a Github action on a regular basis. The output is available at:
Simplest is to install using pipx:
pipx install git+https://github.com/datadavev/mnstatus
A development install can be made using Poetry:
mkvirtualenv mnstatus
git clone https://github.com/datadavev/mnstatus.git
cd mnstatus
poetry install
Usage: mnstatus [OPTIONS] COMMAND [ARGS]...
Options:
--verbosity TEXT Specify logging level [default: INFO]
-J, --json Output in JSON
-C, --cnode_url TEXT Base URL of Coordinating Node
--solr_url TEXT Solr URL absolute or relative to CN base URL.
--help Show this message and exit.
Commands:
nids List nodes from CN node list
node Check node status
To check a single member node, use the node operation:
sage: mnstatus node [OPTIONS] NODE_ID
Options:
-T, --timeout FLOAT HTTP connection timeout in seconds
-t, --test TEXT Tests to run
--help Show this message and exit.
Four tests are available:
ping: Ping the node
mn: Get the number of records, the oldest and most recent System Metadata Modified date as reported by the MN
cn: Get the number of records, the oldest and most recent System Metadata Modified date as reported by the CN
index: Get the number of records, the oldest and most recent System Metadata Modified date and Uploaded date as reported by the CN index.
Counts and times are based on the DataONE listObjects response, which only includes
dateModified. Hence the entries in the status results are the earliest and latest dates
that system metadata was modified.
Example:
mnstatus node urn:node:KNB -t ping -t mn -t cn -t index

To check a bunch of registered nodes, use the nids operation:
Usage: mnstatus nids [OPTIONS]
Options:
-n, --n_type TEXT Specify node type, mn or cn
-s, --state TEXT Specify node state, up or down
-F, --full Show full node records
-t, --test TEXT Tests to run
-T, --timeout FLOAT HTTP connection timeout in seconds
--help Show this message and exit.
For example, check all the member nodes listed as being in the up state:
mnstatus --json nids -n mn -s up -t ping -t index -t mn -t cn -F > test.json
The resulting JSON file is pretty big, and is a JSON-ification of
the XML node list with a status entry added to each node. That
entry contains information similar to the output above for a single node.
A summary can be generated using jq to extract values. For example with columns
node_id, ping_status, mn_count, cn_count, index_count:
curl -s 'https://raw.githubusercontent.com/datadavev/mnstatus/main/data/node_status.json' | \
jq -r '.[] | '\
'[.identifier, .status.ping.status, .status.mn.count, .status.cn.count, .status.index.count ]'\
'| @csv'
