Querying a number (uptime in this case) from an infrastructure device
var ip="172.21.40.254" //Set Ip address var thisDevice = actions.getDevice(ip); //Get managed device if (thisDevice != null) { //Check if it exists in the system var uptime = actions.querySNMPNumber(thisDevice, '.1.3.6.1.2.1.1.3.0', -1); //Query device for uptime and store log.warn('Uptime for device ' + ip+" "+thisDevice.getName()+" "+uptime); //Write information to log }else{ log.warn("No such managed device "+ip); //Alert that device isn't a known infrastructure device }
Querying a String (sysName in this case) from an infrastructure device
var ip="172.21.40.254" //Set Ip address var thisDevice = actions.getDevice(ip); //Get managed device if (thisDevice != null) { //Check if it exists in the system var uptime = actions.querySNMPText(thisDevice, '.1.3.6.1.2.1.1.5.0', -1); //Query device for OID .1.3.6.1.2.1.1.5.0(sysName) and store log.warn('sysName for device ' + ip+" "+thisDevice.getName()+" "+uptime); //Write information to log }else{ log.warn("No such managed device "+ip); //Alert that device isn't a known infrastructure device }
Querying a String (sysName in this case) from an infrastructure device
var ip="172.21.40.254" //Set Ip address var thisDevice = actions.getDevice(ip); //Get managed device if (thisDevice != null) { //Check if it exists in the system var table = actions.querySNMPTable(thisDevice, ['.1.3.6.1.2.1.1']); //Query device for table(s) and store for (var i=0;i<table.size();i++){ var entry = table.get(i); log.warn("This Row:"+i+" :"+entry.getIndex()+" "+showSNMPVariables(entry.getColumns())); } }else{ log.warn("No such managed device "+ip); //Alert that device isn't a known infrastructure device } //A function to return the variables from each returned column function showSNMPVariables(entry){ var retValue=""; for (var i=0;i<entry.length;i++){ retValue+='\t'+i+':'+entry[i].getVariable().toString() } return retValue; }
Getting the SysOID of a device and determining if its a Cisco device
var ip="172.21.40.254" //Set Ip address var thisDevice = actions.getDevice(ip); //Get managed device if (thisDevice != null) { //Check if it exists in the system log.warn('sysOID for device ' + ip+" "+thisDevice.getName()+" "+thisDevice.getSysOID()); //Write details to log if (thisDevice.getSysOID().indexOf('1.3.6.1.4.1.9')==0){ //Look for Ciscos OID and see if it exists ==0 log.warn("Is Cisco");//Write to log } }else{ log.warn("No such managed device "+ip); //Alert that device isn't a known infrastructure device }
If you know the snmp information for a device which isn't an infrastructure device, you can also query that direcly by providing the required params
Querying a number
//querySNMPNumber(String ip, int port, int version, int retries, int timeout, String community, String oid, long adefault) var uptime = actions.querySNMPNumber("172.21.40.254",161,2,1,1000,"th1s1s1t", '.1.3.6.1.2.1.1.3.0', -1); //Query device for uptime and store
Querying a String
//querySNMPText(String ip, int port, int version, int retries, int timeout, String community, String oid, String adefault) var sysname = actions.querySNMPText("172.21.40.254",161,2,1,1000,"th1s1s1t", '.1.3.6.1.2.1.1.5.0', -1); //Query device for sysname and store
Querying a table
//querySNMPTable(String ip, int port, int version, int retries, int timeout, String community, String[] oids) var table = actions.querySNMPTable("172.21.40.254",161,2,2,1000,"th1s1s1t", ['.1.3.6.1.2.1.1']); //Query device for OID .1.3.6.1.2.1.1(system) and store
Processing table results
var table = actions.querySNMPTable("1.2.3.4",161,2,2,1000,"acommunity", ['.1.3.6.1.4.1.9.9.315.1.2.3.1.3.10012']); //Query device for OID .1.3.6.1.2.1.1(system) and store log.warn(table); for (var i=0;i<table.length;i++){ var cols=table[i].getColumns(); log.warn("cols:"+cols.length); log.warn(cols);
for (var c=0;c<cols.length;c++){ log.warn(cols[c]); log.warn("c:"+c);
log.warn(cols[c].getOid()); //1.3.6.1.4.1.9.9.315.1.2.3.1.3.10012.212.129.215.245.100.43.10 = 3
log.warn(cols[c].getVariable().toString()); //3 log.warn(cols[c].getVariable().toInt()); //3 log.warn(cols[c].getVariable().toLong()); //3 } }
