Error message
formatting
A log file is created in the BASEDIR/smarts/local/logs directory for
each
VMware Smart Assurance
application that is started with the
--
output option. (Any
VMware Smart Assurance
application that is installed as a service automatically has
--
output in its invocation.) The log file is the
primary tool for tracking the startup and progression of an
VMware Smart Assurance
application, and for resolving application and discovery errors.
Below figure shows through example the formatting structure of error
(exception) messages that are written to an
VMware Smart Assurance
log file.
VMware Smart Assurance
exception message formatting
The first line of an error message identifies the following information:
- VMware Smart Assurancesoftware subsystem that reported the error
- Severity level of the error:
- F for Fatal
- E for Error
- W for Warning
- N for Notice
- I for Informational
- D for Debug
- Name of the error table from which theVMware Smart Assurancesubsystem took the error
- Name of the errorIn the example error message, the reporting subsystem is ASL, for Adapter Scripting Language, the message severity level is Warning, the error table name is ERROR_RULE_SOURCE, and the error name is “While executing rule set.” The combination of an error table name and an error name uniquely identifies a particular error.The remaining lines in a message, referred to as chained exceptions, provide more detail about the exception appearing in the top line. The last chained exception identifies the root cause of the error. In the example message, the root cause of the error is that the code was instructed to open a file that it could not find.Below table identifies and briefly defines some of theVMware Smart Assurancesubsystems.
VMware Smart Assurance subsystem
| Description
|
|---|---|
ASL
| Adapter scripting language subsystem. (Most
VMware Smart Assurance Adapters are implemented in ASL code.) Throws errors
that are detected by ASL code.
|
DNS
| Network name translation subsystem
|
DVST
| Device status polling subsystem
|
DX
| Correlator subsystem
|
ICF
| VMware Smart Assurance framework subsystem
|
ICS
| VMware Smart Assurance service assurance subsystem
|
MR
| Repository manager. Throws generic Repository errors; the
Repository is the database that stores the discovered topology (inventory).
|
OSA
| Operating system accessor
|
RTLD
| Module loading. Throws errors due to configuration problems that
cause the code to be unable to locate parts of itself.
|
TOPO
| Topology
|
<SYS>
| Not an
VMware Smart Assurance subsystem; represents an operating system component
that threw an error.
