Config file format
Either JSON or YAML notation can be used to create the configuration file, with file extensions of .json and .yaml/.yml, respectively.
YAML is strongly recommended, as it is easier to edit/read/understand compared to JSON.
The parameters in the config file are described below. All parameters must be defined in the config file - run time errors are likely to occur otherwise. The sample config file looks like this:
A few things to keep in mind:
- Topic names (e.g. “Butler-SOS.logdb”) are case sensitive.
- First time Butler SOS is started, a new InfluxDB database will be created, together with a default InfluxDB retention policy
|logLevel||The level of details in the logs. Possible values are silly, debug, verbose, info, warn, error (in order of decreasing level of detail).|
|fileLogging||true/false to enable/disable logging to disk file|
|logDirectory||Subdirectory where log files are stored|
|enableLogDb||Should Sense log db be queried for warnings/errors/info messages? true/false|
|pollingInterval||How often to query log db. Milliseconds|
|queryPeriod||How far back should log db be queried? Human readable, e.g. “5 minutes” (which is also the default value)|
|host||IP or FQDN of server where Sense log db is running|
|port||Port used by log db. 4432 unless changed during installation of Sense|
|qlogsReaderUser||User to connect to log db as. “qlogs_reader” unless changed during installation of Sense|
|qlogsReaderPwd||Password of above user|
|extractErrors||Should error entries be extracted from log db? true/false|
|extractWarnings||Should warning entries be extracted from log db? true/false|
|extractInfo||Should info entries be extracted from log db? true/false.
NOTE: If info level logging is enabled, this will result in lots of messages being stored in Influxdb (at least for a busy Sense cluster).
|clientCert||Certificate file. Exported from QMC|
|clientCertKey||Certificate key file. Exported from QMC|
|clientCertCA||Root certificate for above certificate files. Exported from QMC|
|enableMQTT||Should health metrics be sent to MQTT? true/false|
|brokerHost||IP or FQDN of MQTT broker|
|baseTopic||The topic to which messages will be posted. Should end with /. For example butler-sos/|
|enableInfluxdb||Should health metrics be stored in Influxdb? true/false|
|hostIP||IP or FQDN of Influxdb server|
|hostPort||Port where Influxdb server is listening. Useful if Influxdb for some reason is not using its standard port of 8086|
|auth.enable||Enable if data is to be stored in a password protected Influxdb database|
|dbName||Database namne in Influxdb to which health metrics will be stored. Database will be created if it does not already exist when Butler SOS is started|
|Name of default retention policy that will be created in InfluxDB database, when that database is created during first execution of Butler SOS|
|Duration during which metrics are kept in InfluxDB. After the duration has passed, InfluxDB will purge all data older than duration from the database. See InfluxDB docs for details on syntax.|
|Should a list of currently active Sense apps be stored in Influxdb? true/false|
|Should a list of Sense apps opened in a user session be stored in Influxdb? true/false|
|Should a list of Sense apps loaded into memory (some apps might not currently be associated with a user session) be stored in Influxdb? true/false|
|pollingInterval||How often to query the Sense healthcheck API|
|serverTagsDefinition||List of tags to add to each server when storing the data in Influxdb. All tags defined here MUST be present in each server’s definition section further down in the config file!|
|servers||List of what servers to monitor. For each server a set of properties MUST be defined.|
|FQDN of server. Domain should match that of the certificate exported from QMC - otherwise certificate warnings may appear. NOTE: You need to specify the port too - should be :4747 unless it’s been changed from default value (very unusual to change this).|
|Human friendly server name|
|Human friendly server description|
|Server’s name as it appears in the
|Control whether user session data should be retrieved for this server|
|Host and port from which to retrieve user session data. Usually on the form servername.mydomain.net:4243|
|A list of key-value pairs. Use to specify for which virtual proxies on this server user session data should be retrieved.|
|serverTags||A list of key-value pairs. Use to provide more metadata for servers. Can then (among other things) be used to created more advanced Grafana dashboards.|
Butler-SOS.serversToMonitor.servers.logDbHost property can be tricky to get right. Easiest way to get the correct value is to look in the Nodes section in the QMC. In the
Host name column you find the host names of the various nodes.
logDbHost should be set to the first part of each host name:
