There is no way to backup Alert Rules configuration in LogicMonitor so I came up with this ConfigSource for LMConfig to keep track of configuration changes to Alert Rules. Groovy Script /* ConfigSource Retrieves and stores the JSON document for alert rules. Define the following custom properties on a collector object: api.accessId api.accessKey api.accountName Mosh Jahán Rentokil Initial May 2017 */ import org.apache.http.HttpEntity import org.apache.http.client.methods.CloseableHttpResponse import org.apache.http.client.methods.HttpGet import org.apache.http.impl.client.CloseableHttpClient import org.apache.http.impl.client.HttpClients import org.apache.http.util.EntityUtils import javax.crypto.Mac; import javax.crypto.spec.SecretKeySpec; import org.apache.commons.codec.binary.Hex; def debugMode = false; def apiAccessId; def apiAccessKey; def apiAccountName; if (debugMode == false) { try { apiAccessId = hostProps.get("api.accessId"); } catch (all) { println "(debug::fatal) Missing custom property api.accessId"; return 1; } try { apiAccessKey = hostProps.get("api.accessKey"); } catch (all) { println "(debug::fatal) Missing custom property api.accessKey"; return 1; } try { apiAccountName = hostProps.get("api.accountName"); } catch (all) { println "(debug::fatal) Missing custom property api.accountName"; return 1; } } else { // Hardcode values for debug here apiAccessId = ""; apiAccessKey = ""; apiAccountName = ""; } def resourcePath = "/setting/alert/rules"; def url = "https://" + apiAccountName + ".logicmonitor.com" + "/santaba/rest" + resourcePath; // Calculate signature epoch = System.currentTimeMillis(); requestVars = "GET" + epoch + resourcePath; hmac = Mac.getInstance("HmacSHA256"); secret = new SecretKeySpec(apiAccessKey.getBytes(), "HmacSHA256"); hmac.init(secret); hmacSigned = Hex.encodeHexString(hmac.doFinal(requestVars.getBytes())); signature = hmacSigned.bytes.encodeBase64(); // HTTP GET CloseableHttpClient httpclient = HttpClients.createDefault(); httpGet = new HttpGet(url); httpGet.addHeader("Authorization" , "LMv1 " + apiAccessId + ":" + signature + ":" + epoch); response = httpclient.execute(httpGet); responseBody = EntityUtils.toString(response.getEntity()); statusCode = response.getStatusLine().getStatusCode(); // Output response if (statusCode == 200) { println "AlertRulesJSON:" + responseBody; } else { println "Request failed " + statusCode; } httpclient.close(); return 0;
