Sqlmon NPM | npm.io

sqlmon

Collects events from SQL Server and saves them to Elasticsearch for further analysis.

You can use sqltop or Kibana to analyze these data.

Installation

npm install -g sqlmon

Sample

$ sqlmon \
    --ss-address sql.example.com \
    --ss-user sa \
    --ss-password p@ssw0rd \
    --es-address elasticsearch.example.com \
    --trace-directory 'c:\trace' \
    --events RPCCompleted SQLBatchCompleted \
    --fields TextData TextDataHash QueryHash LoginName Duration Reads Writes CPU \
    --duration 60s

Usage

Trace directory

sqlmon needs to write trace files to a temporary directory on the server first. Use the ---trace-directory option to specify the location of this directory:

--trace-directory 'c:\trace'

Note 1: The SQL Server service account (usually NT Service\MSSQLSERVER) must have Write permission on this directory.

Note 2: These files are not removed when the program ends and must be manually deleted.

Duration

Use the --duration or -d parameter to specify the duration that the trace must run:

--duration 1m

You can use any specifier like 30s, 10m, 2h, or 1d. The default is 60s.

Max trace size

By default, sqlmon limits the size of trace files to 1 GB. You can change this by using the --max-size option (in megabytes):

--max-size 2048 # 2 GB

Events to capture

Use the --events parameter to specify the events to be captured:

--events RPCCompleted SQLBatchCompleted

See all supported events.

Fields to include

Use the --fields parameter to specify the fields to be included:

--fields TextData Reads Writes CPU Duration RowCounts

See all supported fields.

Index name

The default Elasticsearch index name is sql-YY.MM.DD which can be changed using the --index-prefix option:

--index-prefix trace-

Collect only

If you only want to collect events without saving them to Elasticsearch, you can use the --collect-only option.

Importing trace files

If you have a saved trace file (created by either sqlmon or SQL Server Profiler), you can import it into Elasticsearch using the --import option:

--import 'c:\trace\20190728042508732.trc'

Delayed start

You can use the --delay option to delay starting the operations until a later time:

--delay 1h

Hooks

There are a few hooks defined that let you run any program at certain stages of the execution:

--schedule-hook ./myscript.sh
--collection-start-hook ./myscript.sh
--collection-end-hook ./myscript.sh
--save-start-hook ./myscript.sh
--save-end-hook ./myscript.sh
--error-hook ./myscript.sh
--interrupt-hook ./myscript.sh

The following environment variables are available to use in your hooks:

SQLMON_SQLSERVER_ADDRESS
SQLMON_SQLSERVER_PORT
SQLMON_SQLSERVER_USER
SQLMON_SQLSERVER_PASSWORD
SQLMON_SQLSERVER_TIMEOUT
SQLMON_ELASTICSEARCH_ADDRESS
SQLMON_ELASTICSEARCH_PORT
SQLMON_ELASTICSEARCH_TIMEOUT
SQLMON_TRACE_DIRECTORY
SQLMON_INDEX_PREFIX
SQLMON_EVENTS
SQLMON_FIELDS
SQLMON_DURATION
SQLMON_MAX_SIZE
SQLMON_BATCH_SIZE
SQLMON_DELAY
SQLMON_COLLECT_ONLY
SQLMON_IMPORT
SQLMON_START_DATETIME
SQLMON_START_TIME
SQLMON_TRACE_FILE_PATH
SQLMON_STOP_DATETIME
SQLMON_STOP_TIME
SQLMON_TRACE_FILE_PATH
SQLMON_ERROR

Computed fields

TextDataHash

TextDataHash is the hash of the TextData field.

QueryHash

QueryHash is created by first removing all parameters and variables from TextData and then hashing it. It is useful for grouping queries to find the top resource consuming ones.

Supported events and fields

See SQL Server Event Class Reference for detailed information about these fields and events.
