Ok, this is the first time I will post a message without a line of code. I am not sure how to go about this task. So I will describe it and maybe someone will have some thoughts.
I use PHP to connect to our many routers and get data using snmp. I have written a script that refreshes itself every 10 secs. It writes the data to a text file. The key element of this data is the Octet counters, or the amount of data that has been transfered both in and out. To keep it simple, I will only talk about outs. In order to find the amount od data being transfered, I have to compare two lines. Then run a calculation on that and then push that data into an array to plot on a chart later on. Here is an example of the file the data is written to: OctetsIn:4300492881|OctetsOut:4300544503|UnixTime:1041629017 OctetsIn:4305184236|OctetsOut:4305234971|UnixTime:1041629031 OctetsIn:4308716675|OctetsOut:4308782481|UnixTime:1041629044 OctetsIn:4312595737|OctetsOut:4312685815|UnixTime:1041629058 OctetsIn:4315910414|OctetsOut:4315961443|UnixTime:1041629072 OctetsIn:4318948400|OctetsOut:4318975102|UnixTime:1041629085 OctetsIn:4322040239|OctetsOut:4322091605|UnixTime:1041629098 OctetsIn:4324981522|OctetsOut:4325033235|UnixTime:1041629111 OctetsIn:4327971528|OctetsOut:4328029496|UnixTime:1041629125 OctetsIn:4332318792|OctetsOut:4332379277|UnixTime:1041629138 OctetsIn:4335594241|OctetsOut:4335635318|UnixTime:1041629153 OctetsIn:4339008729|OctetsOut:4339048246|UnixTime:1041629166 OctetsIn:4342539875|OctetsOut:4342591776|UnixTime:1041629180 OctetsIn:4346070439|OctetsOut:4346127821|UnixTime:1041629193 OctetsIn:4350288360|OctetsOut:4350355417|UnixTime:1041629206 I can open the file and read the contents line by line split up but the delimiters and get the data I need....but this is what has to happen. If PHP is on line 1, do nothing (it's needs two lines to compare against) If it's on line 2, then subtract Line 1, OctetsOut from Line Line 2 OctetsOut. Then do the same with the UnixTime. Now run a calculation on that data and push that into an array as the first data point. Now move on, with a loop I would assume, and do the same for lines 2 and 3, and so on, until we reach the end. There could be 5 lines or 500 lines..... I can loop through the file and do everything, the biggest problem I am having is getting the data on the line PHP is currently on, and then subtracting the line prior to it. I just can't seem to get a grasp on it. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
