26-Jan-11 3(24) 1. GENERAL The document describes how to setup and use SNMP Monitoring for Luminato to look at the state of the device. Luminato supports SNMP versions 1 and 2c, and generates traps (see Traps). It has implemented MIBs (see List of supported MIBs) and provides mechanisms to detect device state changes when warnings/error/ raised and released (example when signal is lost and returned back). This document does not describes how the SNMP working in general, how to use your MIB Browser nor management system. Statuses can be seen via WebUI at main page:

26-Jan-11 4(24) SNMP Monitoring provides equal view and traps using industry standard MIBs (for more information visit http://www.scte.org/):

26-Jan-11 9(24) 3. SNMP SETUP 3.1. Download MIBs All actual MIBs can be downloaded from device (assumed that standard MIBs are available for you system\browser): Navigate to Administration->Service page Click Download MIBs link See picture:

26-Jan-11 10(24) 3.2. Communities User can read SNMP OIDs and write available using up to 5 different communities for read and write access. Community can be configured via WebUI Administration->Services->Edit SNMP Settings page: Default community are: public (for read only access) private (for write only access)

26-Jan-11 11(24) 3.3. Trap destinations To be able receive traps form Luminato user must register IP(s) to where traps shall be send at the device. Luminato supports up to 5 trap destination. By default none of those are configured. Those can be configured via WebUI Administration->Services->Edit SNMP Settings page: Or via SNMP controltrapreceivertable (1.3.6.1.4.1.3715.99.1.3.5): SNMP interface to trap destination definitions provide more advanced options. By default it uses port 162 and public community.

26-Jan-11 12(24) 4. ALARMS CONCEPTION Device has set of functionality implemented internally by application, drivers, and others subsystems. The states of functionality is represented according to product specific MIB(s) and\or by industry standard MIB(s). Monitored states summarised in discretepropertytable and propertytable (see SCTE-HMS-PROPERTY-MIB). When monitored functionality changes its states, its record in discreteproperty- Table or propertytable changes state. Records from discretepropertytable and propertytable which has alarm state are published in currentalarmtable (see SCTE-HMS-PROPERTY-MIB). When record in currentalarmtable changes it state, added, or removed, new record into hecommonlogtable (see SCTE-HMS-HE-COMMON-MIB) is inserted. If size of hecommonlogtable table became over limit, older records removed. When new record inserted into currentalarmtable the SNMP trap hecommonalarmevent (see SCTE-HMS-HE-COMMON-MIB) is generated and send. Luminato specific note: due to huge set of real monitored object Luminato publish in discretepropertytable only status codes with no references to real monitored objects.

26-Jan-11 13(24) 5. TRAPS 5.1. General Luminato generates traps when device changes state of internal object. Management\Monitoring system should receive those to be aware of device problems. 5.1.1. coldstart Trap coldstart is sent when SNMP subsystem is up and detects device boot up. The trap has two additional bindings: Device type (system object id) Device name The Luminato always reports sysobjectid.0 as 1.3.6.1.4.1.3715.17 (luminato)

26-Jan-11 14(24) 5.1.2. hecommonalarmevent The hecommonalarmevent trap is described by SCTE MIBs. Trap hecommonalarmevent is sent when device s one of objects changed it state. The trap indicates object id, state, date and time, and text message. Those fields are taken from record in hecommonlog which caused trap. State hecommondiscreteminor(7) or hecommondiscretemajor(6) indicates that state arise. State hecommonnominal(1) indicates that state of object returned to its normal(nominal) state. It means that problem resolved. Rest of values for state are reserved for analog parameters and currently not used.

26-Jan-11 15(24) 6. MONITORING 6.1. General The general state of device can be seen on WebUI main page: When status changes it state it is recorded in syslog as well. The SNMP checks status changes with interval of 10 seconds. It means that there absolutely no needs to poll SNMP with higher frequency. Also it means that state which active less than 10 seconds and happened between SNMP checks wont be indicated by SNMP.

26-Jan-11 16(24) 6.2. Active When user\system wants to monitor device state actively it has to poll device not frequently than once per 10 seconds. Summary of current alarm states can be seen via currentalarmtable (1.3.6.1.4.1.5591.1.1.2): Nominal states are not indicated in this table. The verbal description for state you have to decide via statuscode tables.

26-Jan-11 17(24) Example state: sciinterfaceid.1.5.1.4097 (1.3.6.1.4.3715.17.2.4.1.1.1.5.1.4097) sciinterfaceid indicates the state for interface level. Checking indexing for sciinterfaceid:

26-Jan-11 18(24) We can see that interfacetypeid is 1 (means input): Module is 5. Interface id is 1. Status code is 4097. To get verbal description we may get row from statuscodeinterfacetable:

26-Jan-11 19(24) The history of state changes can be seen via hecommonlogtable (1.3.6.1.4.1.5591.1.11.2.1.1.1.2.3): The information on hecommonlogtable can be taken from hecommonloglastindex(1.3.6.1.4.1.5591.1.11.2.1.1.1.2.2.0) and hecommonlognumberofentries(1.3.6.1.4.1.5591.1.11.2.1.1.1.2.1.0) Advanced monitoring system may scan whole hecommonlogtable only when he- CommonLogLastIndex or hecommonlognumberofentries are changed. See Recommended polling strategy.

26-Jan-11 20(24) 6.3. Passive When user\system wants to monitor device state passively it has to register its IP at Luminato (see Trap destinations) and listen for traps. This method is highly recommended as it lets to monitor many devices same time with no performance impact to monitoring system nor monitored device(s). When user\monitoring system receives trap the trap can be decoder according to MIBs to detect what kind of even happens Example: We received a trap: The device IP which send trap is 10.2.12.83 Its uptime is over 2 days (see Binding #1) The trap is hecommonalarmevent (see Binding #2) Decoding Binding #3 we can see: o o Trap send for module level Module ID is 7 what is equal to PSU o Status code is 6 o Additional value is 48 Trap was send due to raised state - Binding #5 indicated hecommondiscretemajor(6) Binding #6 indicated date/time when even was recorded Binding #7 has verbal description of trap

26-Jan-11 21(24) The variables for this trap were taken from hecommonlogtable: 6.4. States Status states may be: hecommondiscreteminor(7)/caasdiscreteminor(7) for statuses level up to warning hecommondiscretemajor(6)/caasdiscretemajor(6) for statuses level error or critical hecommonnominal(1) for statuses which are not raised at moment. Rest of states are reserved for analog parameters and currently not used. 6.5. Recommended polling strategy Regular management system will not poll device but operates base on received traps. If your management system has to poll device, the interval between polls shall be more than 10 seconds. To monitor current state currentalarmtable has to be polled. If verbal definition for state needed, value from one of statuscode tables shall be read. More advanced system shall poll hecommonlognumberofentries (1.3.6.1.4.1.5591.1.11.2.1.1.1.2.1.0) and hecommonloglastindex (1.3.6.1.4.1.5591.1.11.2.1.1.1.2.2.0), and if any of those changed its value read hecommonlogtable (1.3.6.1.4.1.5591.1.11.2.1.1.1.2.3): The whole table can be read Or only new record(s) in hecommonlogtable can be read (base on previous and new values of hecommonloglastindex) Avoid polling of all others tables!!!
