Sybase database size
Purpose
Disk space is a critical resource for any database, to persist database and log data. This monitor is meant to detect situations where allocated disk space is running low.
Configuration hints
Surveillance table:
- This is a table of rules that you can use to configure and customize the configuration.
- Each line of the table will define a rule of monitoring.
- You can combine multiple rules to cover different cases.
- Within a rule, you can configure a maximum data and log used space.
Maximum data and log used space:
- Use the multi-threshold syntax to set multiple threshold/severity associations: G2W:80 W2M:85 (Green To Warning, Warning To Major, etc…).
- An alarm of the corresponding severity will be sent if the used space is reaching a threshold.
- Set 0 in the field if unused
- You can set a DB specific rule by using the DB name filter. Use * to match any DB name, or regular expression.
Rules order:
- Rules are processed following their order in the table.
- One given DB can only be processed once, it will be ignored by subsequent rules.
- Therefore you MUST define specific rules (for a given DB) before general ones (for all).
Surveillance table
| Parameter | Description |
|---|---|
| Active | If checked, the rule is enabled and will be processed |
| DB name | A filter to match only a specific DB name, can use regular expression, white or black list |
| Max DATA used space (%) | The threshold for the DATA usage on disk. You can use the multi threshold syntax (Like G2W:80 W2C:90) |
| Max LOG used space (%) | The threshold for the LOG usage on disk. You can use the multi threshold syntax (Like G2W:80 W2C:90) |
| Severity | The default severity used if multi threshold syntax is not used. |
| Auto clear | If set, clears the alarms that are no longer generated. |
| Alarm tag | This field allows to add custom text within the alarm message. %MSG% variable will contain the actual generated message and can be used such as: “my_prefix %MSG% my_suffix”. By default, tag will be used as prefix. |
| Alarm | Defines if the alerting is active for this rule. |
| Metric | Defines if the metric generation is active for this rule. |
| Report | If checked, this rule will be used for showing threshold and severity in the daily report |
Examples
| Active | DB name | Max DATA used space (%) | Max LOG used space (%) | Severity | Auto clear | Prefix | Alarm | Metric | Report |
|---|---|---|---|---|---|---|---|---|---|
| true | * | 85 | 90 | MAJOR | true | true | true | false |
Effect : A MAJOR alarm will be sent if DATA space is used at 85% of more (and 90% for LOG space), for any database.
Examples
| Active | DB name | Max DATA used space (%) | Max LOG used space (%) | Severity | Auto clear | Prefix | Alarm | Metric | Report |
|---|---|---|---|---|---|---|---|---|---|
| true | master | 0 | G2W:90 W2C:95 | MAJOR | true | true | true | false |
Effect : A WARNING alarm will be sent if LOG space of master DB is used at 90% or more (CRITICAL if 95%)
Generated metrics
| metricId | metricUnit | metricTarget | metricDescription |
|---|---|---|---|
| DATABASE_LOG_PERCENTAGE_USED_SPACE | % | [DB NAME] | The LOG percentage usage of a given DB |
| DATABASE_DATA_PERCENTAGE_USED_SPACE | % | [DB NAME] | The DATA percentage usage of a given DB |
| DATABASE_LOG_USED_SPACE | GB | [DB NAME] | The LOG usage of the DB |
| DATABASE_DATA_USED_SPACE | GB | [DB_NAME] | The DATA usage of the DB |
| DATABASE_TOTAL_LOG_SPACE | MB | [DB NAME] | The total LOG space of the given DB |
| DATABASE_TOTAL_DATA_SPACE | GB | [DB NAME] | The total DATA space of the given DB |
