scalert

Real time alert template.

Description

This module executes custom scripts upon arrival of objects or updates. It provides as template for custom modification and is not a replacement for scvoice.

There are four possible trigger mechanisms for calling scripts:

  • Event creation/update,

  • Amplitude creation,

  • Origin creation (with status = preliminary),

  • Pick creation with filter for phase hint.

Note

People started modifying scvoice to send emails or other alert messages. Then, the name scvoice is then just wrong. If you want to customize scvoice, use scalert instead.

Configuration

etc/defaults/global.cfg
etc/defaults/scalert.cfg
etc/global.cfg
etc/scalert.cfg
~/.seiscomp/global.cfg

scalert inherits global options.

firstNew

Type: boolean

Treat an event as new event when it is seen the first time. Default is false.

agencyIDs

Type: list:string

List of agencyIDs to consider picks and origins. The agencyID is extracted from the pick or the preferred origin of the event and compared with the configured IDs.

unset (=): use agencyID defined in global, default

empty list (=""): all agencies are allowed

poi.message

Type: string

The default message string for the event-script is "earthquake, [HOURS] hours [MINS] minutes ago, [DESC], magnitude [MAG], depth [DEP] kilometers" whereas [DESC] is the string given in the event.description attribute. This string can be overwritten using one of the following options. There are three placeholders that can be used: @region@, @dist@ and @poi@. Example: "@region@, @dist@ kilometers from @poi@ away".

poi.maxDist

Type: double

Unit: deg

When using the nearest point of interest (city) as part of the message string, specify the maximum distance in degrees from the event. Any point of interest farther away will be ignored. Default is 20.

poi.minPopulation

Type: double

Minimum population for a city to become a point of interest. Default is 50000.

scripts.pick

Type: string

The script to be called when a pick arrives. Network-, station code, pick publicID are passed as parameters $1, $2, $3.

scripts.amplitude

Type: string

The script to be called when an amplitude arrives. Network-, station code, amplitude and amplitude publicID are passed as parameters $1, $2, $3, $4.

scripts.alert

Type: string

The script to be called when a preliminary origin arrives. Latitude and longitude are passed as parameters $1 and $2.

scripts.event

Type: string

The script to be called when an event has been declared. The message string, a flag (1=new event, 0=update event), the EventID, the arrival count and the magnitude (optional when set) are passed as parameters $1, $2, $3, $4 and $5.

Note

constraints.* Constraints for executing scripts

constraints.phaseHints

Type: list::string

Start the pick script only when the phaseHint of the received pick has one of the value(s). Default is P,S.

Command-line

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.

--first-new

Overrides configuration parameter firstNew.

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.

--content-type arg

Overrides configuration parameter connection.contentType.

--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

Alert

--amp-type arg

Specify the amplitude type to listen to.

--amp-script arg

Overrides configuration parameter scripts.amplitude.

--alert-script arg

Overrides configuration parameter scripts.alert.

--event-script arg

Overrides configuration parameter scripts.event.

Cities

--max-dist arg

Overrides configuration parameter poi.maxDist.

--min-population arg

Overrides configuration parameter poi.minPopulation.

Debug

-E, --eventid arg

Specify event ID that is used for testing. After running the alert scripts scvoice will exit.
