This is the official Python client library for the Argus API server.
The Argus server is an incident registry, capable of aggregating alerts from multiple source systems. Argus also can send event notifications (via e-mail, SMS, etc.) when incidents are created or resolved.
The pyargus library models the official API endoints of Argus as methods on an API client object.
At the moment, only the methods and models needed to interact with incident-related endpoints are supported.
The Client
class is found in pyargus.client
, and the various supported data
models, such as Incident
, Event
, Acknowledgement
and SourceSystem
, are
implemented in pyargus.models
.
>>> from pyargus.client import Client
>>> c = Client(api_root_url="https://argus.example.org/api/v2", token="foobar")
>>> for incident in c.get_incidents(open=True, acked=False):
... print(incident)

As you can see, the arguments given to get_incidents()
are translated
verbatim into the arguments supported by the /incidents
endpoint in the API.
The incidents API also has an /incidents/mine
endpoint, which works just like
the /incidents
endpoint, but searches only the incidents that were posted
by the connecting user. This is useful for glue services, when they need to
compare the list of open Argus incidents it has produced with the current list
of active alerts in its source system.
Example:
>>> from pyargus.client import Client
>>> c = Client(api_root_url="https://argus.example.org/api/v2", token="foobar")
>>> for incident in c.get_my_incidents(open=True, acked=False):
... print(incident)
...
Incident(pk=3, start_time=datetime.datetime(2021, 4, 4, 16, 32, 53, 128780, tzinfo=datetime.timezone(datetime.timedelta(seconds=7200), '+02:00')), end_time=datetime.datetime(9999, 12, 31, 23, 59, 59, 999999), source=SourceSystem(pk=3, name='foobar, type='nav', user=4, base_url='http://localhost/'), source_incident_id='2716057', details_url='http://localhost/search/event/2716057', description='uninett-gsw1 BGP session with 158.38.3.112 is DOWN', level=5, ticket_url='', tags={'location': 'Teknobyen Innovasjonssenter', 'kundetjeneste': 'Nett_CNaaS', 'kunde': 'example.org', 'event_type': 'bgpState', 'alert_type': 'bgpDown', 'host': 'uninett-gsw1.uninett.no', 'room': '100', 'organization': 'uninett.srv'}, stateful=True, open=True, acked=False)
>>> from pyargus.client import Client
>>> from pyargus.models import Incident
>>> from datetime import datetime
>>> c = Client(api_root_url="https://argus.example.org/api/v2", token="foobar")
>>> i = Incident(
... description="The earth was demolished to make way for a hyperspace bypass",
... start_time=datetime.now(),
... tags={
... "host": "earth.example.org",
... }
... )
>>> c.post_incident(i)
Incident(pk=8, start_time=datetime.datetime(2021, 4, 22, 11, 41, 53, 580947, tzinfo=datetime.timezone(datetime.timedelta(seconds=7200), '+02:00')), end_time=None, source=SourceSystem(pk=2, name='testnav', type='nav', user=3, base_url='http://localhost/'), source_incident_id='', details_url='', description='The earth was demolished to make way for a hyperspace bypass', level=5, ticket_url='', tags={'host': 'earth.example.org'}, stateful=False, open=False, acked=False)
The post_incident()
method returns the full Incident
record, as stored in
Argus. If you need it, you can get the incident ID from the the primary key
attribute pk
, in case you need to address it directly later.
Incidents are closed by posting a END type event to an incident's event
log, with an optional timestamp. The Client
class provides the follow
convenience method for this operation:
>>> from pyargus.client import Client
>>> from datetime import datetime
>>> c = Client(api_root_url="https://argus.example.org/api/v2", token="foobar")
>>> c.resolve_incident(incident=8, description="The demolition was cancelled", timestamp=datetime.now())
Event(pk=10, actor='testnav', description='The demolition was cancelled', incident=8, received=datetime.datetime(2021, 4, 22, 11, 47, 11, 978438, tzinfo=datetime.timezone(datetime.timedelta(seconds=7200), '+02:00')), timestamp=datetime.datetime(2021, 4, 22, 11, 47, 11, 946076, tzinfo=datetime.timezone(datetime.timedelta(seconds=7200), '+02:00')), type='END')
Argus does not allow modification of most incident attributes, but things
like the tag list can be changed. Modifications are made by constructing an
Incident
object with the pk
attribute set to the id of the incident you
wish you modify, and then adding values to the attributes you wish to modify:
>>> from pyargus.client import Client
>>> from pyargus.models import Incident
>>> from datetime import datetime
>>> c = Client(api_root_url="https://argus.example.org/api/v2", token="foobar")
>>> i = Incident(
... pk=8,
... tags={
... "host": "earth.example.org",
... "location": "Milky way",
... }
... )
>>> c.update_incident(i)
Incident(pk=8, start_time=datetime.datetime(2021, 4, 22, 11, 41, 53, 580947, tzinfo=datetime.timezone(datetime.timedelta(seconds=7200), '+02:00')), end_time=None, source=SourceSystem(pk=2, name='testnav', type='nav', user=3, base_url='http://localhost/'), source_incident_id='', details_url='', description='The earth was demolished to make way for a hyperspace bypass', level=None, ticket_url='', tags={'host': 'earth.example.org', 'location': 'Milky way'}, stateful=False, open=False, acked=False)
Argus supports a concept of "stateless" incidents. Stateless incidents
represent single points in time, and do not have an end time. To explicitly
create stateless incidents, set the end_time
attribute to the STATELESS
sentinel, like so:
from datetime import datetime
from pyargus.models import Incident, STATELESS
stateless_incident = Incident(
description="Something happened",
start_time=datetime.now(),
end_time=STATELESS
)
