Environment variables
Prerequisites
For setting configuration file properties such as location and path:
First, you should set some environment variables for the locate configuration file.
There are two options here, you can get the configuration file from a local drive or by using git.
For reading configuration files from a local drive:
Set
OEC_CONF_SOURCE_TYPE
andOEC_CONF_LOCAL_FILEPATH
variables.
For Redhat 6 / Centos 6 edit the /etc/init.d/oec file add these 2 export commands just before the "start()" function:
/etc/init.d/oec
export OEC_CONF_SOURCE_TYPE="local" export OEC_CONF_LOCAL_FILEPATH="/home/jsm/jec/config.json" start().......
For Redhat 7 / Centos 7 and Debian / Ubuntu edit the /etc/systemd/system/oec.service file, inside the [Service] key add the following "Environment" properties just before the start of the [install] key:
/etc/systemd/system/oec.service
... [Service] ... ... Environment="OEC_CONF_SOURCE_TYPE=local" Environment="OEC_CONF_LOCAL_FILEPATH=~/oec/config.json" ... [Install]
For Windows Sytems edit the oecService<32 | 64>.json file provided in the zip file you downloaded when you followed the instructions on our "Installation" page. The JSON contains a key called "Env" it takes an array as its value, lists the "OEC_CONF_LOCAL_FILEPATH" and "OEC_CONF_SOURCE_TYPE" with their values within the "Env" key's array.
JSON
... ... "Env": [ "OEC_CONF_LOCAL_FILEPATH=C:\\opsgenie\\oec-win64\\config.json", "OEC_CONF_SOURCE_TYPE=local" ], ... ...
From reading configuration files from a git repository:
Set
OEC_CONF_GIT_URL
,OEC_CONF_GIT_FILEPATH
,OEC_CONF_GIT_PRIVATE_KEY_FILEPATH
, andOEC_CONF_GIT_PASSPHRASE
variables.
If you are using a public repository, you should use an https format of a git url and you do not need to set private key and passphrase.
You can set
OEC_API_KEY
variable (optional), if this property is set in the environment its value will be used as apiKey otherwise apiKey from configuration file (mentioned below) will be used.
Key | Value Properties | Example |
---|---|---|
OEC_CONF_SOURCE_TYPE | git → For getting from git local → For getting from local environment | OEC_CONF_SOURCE_TYPE=git |
OEC_CONF_LOCAL_FILEPATH | filepath with extension (.yaml, .yml or .json) | OEC_CONF_LOCAL_FILEPATH=/home/JSM/OECConfig.yaml |
OEC_CONF_GIT_URL | HTTPS or SSH url of the git repository | OEC_CONF_GIT_URL=git@bitbucket.com:metehan/test-private-conf-cem.git |
OEC_CONF_GIT_FILEPATH | filepath in the git repository folder (.yaml, .yml or .json) | OEC_CONF_GIT_FILEPATH=~/oec/config.json |
OEC_CONF_GIT_PRIVATE_KEY_FILEPATH | git ssh key location in local drive | OEC_CONF_GIT_PRIVATE_KEY_FILEPATH=~/.ssh/id_rsa |
OEC_CONF_GIT_PASSPHRASE | ssh passphrase | OEC_CONF_GIT_PASSPHRASE=1234 |
OEC_LOG_FORMAT_TYPE | text → logrus text type logs | OEC_LOG_FORMAT_TYPE=text |
OEC_API_KEY | API key from Opsgenie’s OEC Integration page, if this property is set it will override apiKey provided in configuration file. | OEC_API_KEY=4XXXXXX7-XXXX-XXXX-XXXX-9XXXXXXXXXX4 |
‘~’ character can be used as home directory for running the program as a user in customer’s server.
Flag
Prometheus default metrics can be grabbed from
http://localhost:<port-number>/metrics
To run multiple JEC in the same environment, -oec-metrics flag should be set as distinct port number values.
-oec-metrics <port-number>
Logs
JEC log file is located:
On Windows:
var/log/opsgenie/oec<pid>.log
On Linux:
/var/log/opsgenie/oec<pid>.log
At the end of the file name of the log, there is program identifier (pid) to identify which process is running.
Configuration File
JEC supports json and yaml file extension with fields. Configuration filepath should be set on
OEC_CONF_LOCAL_FILEPATH
or
OEC_CONF_GIT_FILEPATH
according to local or git choice.
Field | Type | Mandatory | Description |
---|---|---|---|
apiKey | string | true | The API key which is copied from the JEC Integration page. |
baseUrl | string | false | The API url of the Jira Service Management mirror
|
logLevel | string | false | Log level of the JEC |
globalArgs | list of string | false | Execute arguments that applies to all actions |
globalFlags | map of string key-value | false | Execute flags that applies to all actions |
globalEnv | list of string | false | Each element indicates one environment variable name and value separated with ‘=’ character. Applies to all actions. (e.g., “ENV1=value”) |
actionMappings | map of string key and mappedAction value | true | Map of the alert action mappings |
actionMappings → mappedAction | map | true | Each mappedAction represents an action and includes an action properties sourceType, filepath, gitOptions and environmentVariables. |
actionMappings → mappedAction → sourceType | string | true | Type of script file location can be ‘local' or 'git’ |
actionMappings → mappedAction → filepath | string | true | Location of script or executable file
|
actionMappings → mappedAction → stdout | string | false | stdout filepath of action |
actionMappings → mappedAction → stderr | string | false | stderr filepath of action |
actionMappings → mappedAction → args | list of string | false | Execute arguments that applies to specified action |
actionMappings → mappedAction → flags | map of string key-value | false | Execute flags that applies to specified action |
actionMappings → mappedAction → env | list of strings | false | Each element indicates one environment variable name and value separated with ‘=’ character. Applies to specified action. (e.g., “ENV1=value”) |
actionMappings → mappedAction → gitOptions | map | true for git source | This field includes all three string properties,
|
actionMappings → mappedAction → gitOptions → url | string | true for git source | HTTPS or SSH url of the git repository of the mappedAction |

pollerConf | map | false | The field gets all three integer properties specifying behavior of the poller that poll the sqs queue of OEC. |

pollerConf → visibilityTimeoutInSeconds | integer | false | The visibility timeout of messages that are polled from sqs queue
|

|
poolConf → monitoringPeriodInMillis | integer | false | Monitoring interval to record pool metrics
|
Local variable of args, flags and env overrides global ones.
apiKey, opsgenieUrl (baseUrl) and payload (JEC callback as JSON) passes to args as flag format. These flags should be parsed in action scripts or executables.
Payload consists alert info and integration specific params. Integration-specific params will exist for “send via JEC” option.
JEC updates git repositories periodically every 1 minute.
JEC integration uses directly actual actions (e.g. Create, Close, Acknowledge, etc.), other integrations will use primarily "mappedAction" related with themselves (e.g. addCommentToIssue, createIssue, etc. for Jira integration).
