source code

Get a cursor for the ZenEventManager connection.

source code

Execute stmt against ZenEventManager connection and return the number of rows that were affected.

source code

query(self, stmt)
Execute stmt against ZenEventManager connection and fetch all results.

source code

_describe(self, stmt)
Execute stmt against ZenEventManager connection and return the cursor description.

source code

_columnNames(self, table)
Returns the column names for the table using a ZenEventManager connection.

source code

getBaseUrl(self, device=None)

source code

getEventUrl(self, evid, device=None)

source code

getEventsUrl(self, device=None)

source code

getAckUrl(self, evid, device=None)

source code

getDeleteUrl(self, evid, device=None)

source code

getUndeleteUrl(self, evid, device=None)

source code

processRules(self, zem)

_getCursor(self, stmt, callback)

source code

Get a cursor for the ZenEventManager connection. Execute statement and call the callback with the cursor and number of row affected.

filterDeviceName(self, zem, whereClause)

source code

This is somewhat janky but we only store the device id in the mysql database but allow people to search based on the device "title". This method resolves the disparity by searching the catalog first and using those results.

deleteHistoricalEvents(self, deferred=False, force=False)

source code

Once per day delete events from history table. If force then run the deletion statement regardless of when it was last run (the deletion will still not run if the historyMaxAgeDays setting in the event manager is not greater than zero.) If deferred then we are running in a twisted reactor. Run the deletion script in a non-blocking manner (if it is to be run) and return a deferred (if the deletion script is run.) In all cases return None if the deletion script is not run.

sendPage(self, action, data, clear=None)

source code

Send and event to a pager. Return True if we think page was sent, False otherwise.

sendEmail(self, action, data, clear=None)

source code

Send an event to an email address. Return True if we think the email was sent, False otherwise.
