Question: How do I run adhoc queries on the Foxhound database?
Answer:
You can use the following connection parameters with dbisql, or with any other query tool that can connect to a SQL Anywhere database:
-c "ENG=foxhound2;DBN=f;UID=ADHOC;PWD=SQL"
Here are the views you can SELECT from; the ones highlighted in bold may be the most useful:
|
alert |
One row per alert. | |
alert_cancelled |
One row per alert cancellation. | |
alert_union |
A view which gathers data from the alert, alert_cancelled, all_clear and sampling_options
views to make reporting easier. | |
alerts_criteria |
One row containing the Monitor Options page settings for each sampling session, plus rows
for 'Factory Settings' and 'Saved Defaults'. | |
all_clear |
One row per alert all-clear. | |
build_number |
A single-row table containing some attributes of the current installation of the Foxhound database. | |
connection_string |
One row for each connection string displayed on the String tab of the Foxhound main menu. | |
data_upgrade_history |
One row for each time the data in an existing Foxhound database has been copied into a new
Foxhound database as part of the installation process. | |
email_failure |
One row for each time Foxhound failed in an attempt to send an Alert or other email. | |
exception_diagnostic |
One row for each time Foxhound detected an error or other important event. In some cases, a
single underlying error may result in two or more rows in exception_diagnostic recorded by
nested exception handlers in Foxhound. | |
exception_dump |
One row for each time Foxhound stored extra internal diagnostic information associated with an
event recorded in exception_diagnostic. | |
expiry_date |
A single-row table containing some attributes of the current installation of the Foxhound database. | |
global_options |
A single-row table containing some options affecting how Foxhound behaves. | |
monitor_sampler_control |
A single-row table containing some information about current execution of the Foxhound database. | |
peaks |
One row for each Foxhound Monitor target database, holding various peak values and links to
the corresponding samples. | |
purge_run |
One row for each run of the Foxhound database purge process, holding information about the
progress of the current run and the work accomplished by previous runs. | |
run_characteristics |
A single-row table containing some information about current execution of the Foxhound database. | |
sample_detail |
One row for each sample recorded by the Foxhound Database Monitor, holding various additional
server and database-level properties and computed columns. | |
sample_connection |
One row for each connection recorded for each Foxhound Database Monitor sample, holding
various connection-level properties and computed columns. | |
sample_header |
One row for each sample recorded by the Foxhound Database Monitor, holding various server
and database-level properties and computed columns. | |
sampling_options |
One row for each Foxhound Monitor target database, holding various options affecting how the
Monitor behaves and information about the current status of the Monitor session. | |
saved_activation_key |
A single-row table containing data that makes it possible to install a new Beta copy of
Foxhound as an upgrade to an existing Basic or Extended edition, and then install a later
GA copy as an upgrade to the existing Beta copy and have it automatically re-activated as a
Basic or Extended edition. | |
serial_number |
A single-row table containing the Foxhound serial number as shown on the About page. | |
session_options |
One row for each HTTP session established during the current execution of the Foxhound database. | |
used_activation_key |
One row for each different key used in the Foxhound activation process. | |
