scinv¶

Inventory database synchronisation.

Description¶

scinv merges inventory XML files to a single inventory, synchronises an inventory with another (most common use is with database), creates initial key files and much more …

scinv is used by etc/init/scinv.py to synchronise the inventory from etc/inventory with the database.

seiscomp update-config inventory

Commands¶

scinv works with different commands. The command must be given as 1st parameter to the application. All others parameters must follow.

scinv $command [options] [files]

sync¶

Synchronises an applications inventory with a given source given as file(s). The applications inventory is either read from the database or given with –inventory-db. As a result all information in the source is written to target and target does not contain any additional information. The source must hold all information. This works different to merge. If an output file is specified with -o no notifiers are generated and sent via messaging.

This command is used by etc/init/scinv.py as follows:

scinv sync --console=1 -H localhost:$p --filebase "$fb" \
           --rc-dir "$rc" --key-dir "$kd"

where

$p = configured messaging port
$fb = $SEISCOMP_ROOT/etc/inventory
$rc = $SEISCOMP_ROOT/var/lib/rc
$kd = $SEISCOMP_ROOT/etc/key

merge¶

Merges two or more inventories into one inventory. This command is useful to merge existing subtrees into a final inventory before synchronization.

scinv merge net1.xml net2.xml -o inv.xml

apply¶

Applies stored notifiers created with sync and option –create-notifer which is saved in a file (-o). Source is the applications inventory read from the database or given with –inventory-db. If -o is passed no messages are sent but the result is stored in a file. Useful to test/debug or prepare an inventory for offline processing.

# Synchronise inventory and save the notifiers locally (no messages
# are sent)
scinv sync -d mysql://sysop:sysop@localhost/seiscomp3 \
      --create-notifier -o sync_patch.xml

# Sent the notifiers to the target system
scinv apply -H localhost sync_patch.xml

This operation can be useful to save synchronisation diffs for validation or to debug problems.

keys¶

Synchronise station key files with current inventory pool. This command merges all XML files in the inventory pool (or the given files) and checks if a corresponding station key file in etc/key exists. If not an empty station key file is created. If a station key file without a corresponding station in the merged inventory is found, it is deleted.

ls¶

List contained items up to channel level. This command is useful to inspect an XML file or the complete inventory pool.

$ scinv ls SK.KOLS.xml
  network SK       Slovak National Network of Seismic Stations
    epoch 1980-01-01
    station KOLS   Kolonicke sedlo, Slovakia
      epoch 2004-09-01
      location __
        epoch 2004-09-01
        channel BHE
          epoch 2006-04-25 12:00:00 - 2010-03-24
        channel BHN
          epoch 2006-04-25 12:00:00 - 2010-03-24
        channel BHZ
          epoch 2006-04-25 12:00:00 - 2010-03-24
        channel EHE
          epoch 2004-09-01 - 2006-04-25 10:00:00
        channel EHN
          epoch 2004-09-01 - 2006-04-25 10:00:00
        channel EHZ
          epoch 2004-09-01 - 2006-04-25 10:00:00
        channel HHE
          epoch 2006-04-25 12:00:00 - 2010-03-24
        channel HHE
          epoch 2010-03-25
        channel HHN
          epoch 2006-04-25 12:00:00 - 2010-03-24
        channel HHN
          epoch 2010-03-25
        channel HHZ
          epoch 2006-04-25 12:00:00 - 2010-03-24
        channel HHZ
          epoch 2010-03-25

The default level of information printed is chan. Available levels are net, sta, chan and resp.

To check the available networks and stations in the inventory pool, calling

scinv ls

is enough.

check¶

Checks consistency of passed inventory files or a complete filebase. In the first step the inventory is merged from all files. In the second step several consistency checks are applied such as:

overlapping epochs on each level (network, station, …)
valid epochs (start < end)
defined gain in a stream
set gainUnit
distance of the sensor location to the station location
“invalid” location 0/0

In future further checks will be added to make this tool a real help for correct meta data creation.

Configuration¶

etc/defaults/global.cfg
etc/defaults/scinv.cfg
etc/global.cfg
etc/scinv.cfg
~/.seiscomp3/global.cfg
~/.seiscomp3/scinv.cfg

scinv inherits global options.

syncKeys¶

Type: boolean

Synchronise key files. Default is true.

purgeKeys¶

Type: boolean

Delete key files if a station does not exist in inventory. Default is true.

Command-line¶

scinv command [options] [files]

Command is one of: sync, merge, apply, keys, ls and check.

Generic¶

-h, --help¶: show help message.

-V, --version¶: show version information

--config-file arg¶: Use alternative configuration file. When this option is used the loading of all stages is disabled. Only the given configuration file is parsed and used. To use another name for the configuration create a symbolic link of the application or copy it, eg scautopick -> scautopick2.

--plugins arg¶: Load given plugins.

-D, --daemon¶: Run as daemon. This means the application will fork itself and doesn’t need to be started with &.

--auto-shutdown arg¶: Enable/disable self-shutdown because a master module shutdown. This only works when messaging is enabled and the master module sends a shutdown message (enabled with –start-stop-msg for the master module).

--shutdown-master-module arg¶: Sets the name of the master-module used for auto-shutdown. This is the application name of the module actually started. If symlinks are used then it is the name of the symlinked application.

--shutdown-master-username arg¶: Sets the name of the master-username of the messaging used for auto-shutdown. If “shutdown-master-module” is given as well this parameter is ignored.

Verbosity¶

--verbosity arg¶: Verbosity level [0..4]. 0:quiet, 1:error, 2:warning, 3:info, 4:debug

-v, --v¶: Increase verbosity level (may be repeated, eg. -vv)

-q, --quiet¶: Quiet mode: no logging output

--component arg¶: Limits the logging to a certain component. This option can be given more than once.

-s, --syslog¶: Use syslog logging back end. The output usually goes to /var/lib/messages.

-l, --lockfile arg¶: Path to lock file.

--console arg¶: Send log output to stdout.

--debug¶: Debug mode: –verbosity=4 –console=1

--log-file arg¶: Use alternative log file.

Messaging¶

-u, --user arg¶: Overrides configuration parameter connection.username.

-H, --host arg¶: Overrides configuration parameter connection.server.

-t, --timeout arg¶: Overrides configuration parameter connection.timeout.

-g, --primary-group arg¶: Overrides configuration parameter connection.primaryGroup.

-S, --subscribe-group arg¶: A group to subscribe to. This option can be given more than once.

--encoding arg¶: Overrides configuration parameter connection.encoding.

--start-stop-msg arg¶: Sets sending of a start- and a stop message.

Database¶

--db-driver-list¶: List all supported database drivers.

-d, --database arg¶: The database connection string, format: service://user:pwd@host/database. “service” is the name of the database driver which can be queried with “–db-driver-list”.

--config-module arg¶: The configmodule to use.

--inventory-db arg¶: Load the inventory from the given database or file, format: [service://]location

--db-disable¶: Do not use the database at all

Manager¶

--filebase dir¶: Filebase to check for XML files. If not given, all XML files passed are checked.

--rc-dir dir¶: If given, rc (resource) files will be created in this directory for each station. The station descriptions will be from the last available epoch.

--key-dir dir¶: If given this directory is used to synchronise key files.

-o, --output file¶: Output file.

--level int¶: Information level reported by ls. One of “net”, “sta”, “cha” or “resp”. Default is “cha”.

--compact¶: Enable compact output for ls: each object one line.

Merge¶

--strip¶: Remove unreferenced objects (dataloggers, sensors, …).

Sync¶

--create-notifier¶: If an output file is given then all notifiers will be saved and not the result set itself.

--no-keys¶: Do not synchronise key files.

--no-rc¶: Do not synchronise rc files.

--purge-keys¶: (default) Delete key files if a station does not exist in inventory.

--no-purge-keys¶: Do not delete key files if a station does not exist in inventory.

--test¶: Do not send any notifiers and just output resulting operations and conflicts.
