Modules generated by the plugin
This plugin can return up to 26 values (modules) for each IP SLA monitor, using the unique denominator of that monitor set on the Cisco device. The available monitors will vary depending on the specific configuration of your device. The monitors used during the development of the plugin are as follows:
- Jitter - A metric that allows you to analyze the variation in packet send and receive delay.
- Echo - The ICMP echo operation monitors the end-to-end response time between a Cisco router and network elements or IP hosts. This response time is calculated by measuring the time between sending an ICMP echo request message to the destination and receiving the ICMP echo response.
ICMP echo response is received.
- Pathecho - The ICMP path echo operation collects statistics for each hop along the path until it reaches its destination. The ICMP path echo operation determines this hop-by-hop response time between a Cisco router and any IP device on the network by discovering the trace with the traceroute tool. As a result, the round-trip delay for the entire path is displayed.
- Udpecho - The results of a UDP echo operation can be useful both for troubleshooting critical applications by testing connectivity on Cisco and non-Cisco devices, as well as for determining round-trip delay times.
round-trip delay times.
- Dlsw - Operation to measure the protocol queue and response time between dlsw. v peers and the IP address of the peer.
- Tcpconnect - This operation allows to monitor the connection status with machines with specific applications that use the TCP protocol.
- http - This operation allows to evaluate the status of the server by measuring the response time between the request from the source machine and the loading of the web page.
- ftp - Allows to monitor the time delay between the request and the download of a file from an FTP server.
- Dhcp - Allows to measure the time between a request and the corresponding response from the dhcp server.
- DNS - Measures the time it takes for a name request to be answered by a DNS server.
- Voip - This operation allows to measure the delay in Voip communications in case of connections during calls and connections with gatekeepers.
The following are the modules that we can collect from each of the above values.
above:
-ICPIF - Factor calculated from the metrics obtained to measure voice quality.
-MOS - Factor that allows to measure the voice quality.
-Packet_Out_of_Sequence - Packets received out of sequence.
-Packet_Late_Arrival - Packets received with delay.
-Average_Jitter - The estimated value of the average jitter observed in the last XX RTP packets.
-PacketLossSD - Packet loss from source to destination.
-PacketLossDS - Packet loss from destination to source.
-PacketLost - Loss of packets whose address is impossible to determine.
-NegativesSD - Sum of the value of all negative jitter values of packets sent from source to destination.
-NegativesDS - Sum of the value of all negative jitter values of packets sent from destination to source.
- PositivesDS - Sum of the value of all positive jitter values of packets sent from source to destination.
- PositivesDS - Sum of the value of all positive jitter values of packets sent from destination to source.
-RTTMax - Maximum packet bend offset time.
-RTTMin - Minimum packet round trip time.
-OperNumOfRTT - Number of successful bent type shifts.
-OperPacketLossSD - Packet loss from source to destination for jitter tests.
-OperPacketLossDS - Packet loss from destination to source for jitter type tests.
-RttOperSense - Code indicating the status of the last RTT type operation.
-RttOperCompletionTime - Time taken for the last RTT operation to complete successfully.
-RttOperTime - System time at the time of the last RTT operation.
-RttOperAddress - Specifies the destination address for the RTT operation.
-HTTPOperRTT - Time required to complete the HTTP operation.
- HTTPOperDNSRTT - Time required to complete the DNS query within the HTTP operation.
-HTTPOperTCPConnectRTT - Time required to connect to the HTTP server.
-IcmpJitterAvgJitter - Average value of positive and negative jitter type values.
-HTTPOperTransactionRTT - Time required to download the object specified by the URL.
