I want to create graphs that displays the uptime of servers for the past month. I use the following create and graph scripts:
"C:\Salive\rrdtool.exe" create "C:\temp\Graph\sa_2.rrd" -s 120 DS:stats_uptime:DERIVE:720:0:U RRA:AVERAGE:0.5:1:21600 "C:\Program Files\Salive\external\rrdtool.exe" graph month_sa_2.png --start now-31d --end now --imgformat PNG --title="Uptime on Server x" DEF:sa_2=sa_2.rrd:stats_uptime:AVERAGE LINE1:sa_2#0000FF:"Up Time" These scripts create a graph. And the graph looks like the first graph in the attached file "graph.png", while what I want is a graph that looks like the second graph, because other statistics generated of this server show that the server has been up since I started the generation of graphs.. Why does the graph look like this when it should be a straight horizontal line? Is it wrong to use AVERAGE? Should I use MAX instead? (And what does LAST do?) Is it correct to use DERIVE? What I want to see is the uptime of the server through out the month. Should I use COUNTER instead? Would that not result in an ever increasing value through out the month? If I use the DERIVE, do I have to restart all the servers to create a starting point? I want a graph that, as long as the server is up all of the 24 hours of the day, shows a straight horizontal line for the entire day. If the server is down it should be set to zero for the time it is down. What should I do with my Create and Graph scripts to achieve this?

Within the update script we do not point to any DS within the database, only to the database. The update script can not be altered. The problem with the spaces in the path, we know about that. This is something that is already fixed in the latest beta builds. Also (just so you know) we're working on several smallish but usefull extensions of the RRD part of Servers Alive. For example SA HTML tags for the graphs, SA HTML tags that can be used within an CASE/IF to see IF RRD is used for that entry. The default CREATE script will propose an "options line" that enables the creation of graphs that are not only for the past hour, but also day/week/month/year. The graph script will by default then also include the commands to create day/week/month/year graphs. The RRD database and the graphs can be in different directories, even per graph type you can have a different directory. All little things that will make the RRD integration a bit better...

This resulted in an error when running the update script, and the databases and graphs where then never updated with new values. For creating graphs with Servers Alive and rrdtool, I run the following command when creating the CREATE script in Servers Alive (Setup-> Logging -> RRDTools ) : -s 120 DS:stats_uptime:DERIVE:720:0:U RRA:AVERAGE:0.5:1:21600 This will create databases for each server of the uptime of each server. What I want is the uptime for each server over a period of a month. I want to collect data every other minute. Is this a correct command to use? Is the stats_uptime the right DS to get the time a server has status up? I have altered the graph script to be as follows: rrdtool.exe graph month_sa_1.png --start now-31d --end now --imgformat PNG --title="Uptime on server xxx" DEF:sa_2=sa_2.rrd:stats_uptime:AVERAGE LINE1:sa_2#0000FF:"Up Time" The update scripts are created automatically by Servers Alive. Will the update script fetch the right data (stats_uptime) ? And if not, is there any way to alter the automatically created update script?

So if you change the existing BAT file (sa_create_graph.bat) you can do anything you want with it. Dirk. _____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Fladsrud Tom Sent: Friday, August 12, 2005 2:53 PM To: [EMAIL PROTECTED] Subject: [SA-list] Generate graphs of up and downtime I am new to using the RRDTools, and I want to generate graphs of up and downtime of servers. I want to display the sum of the downtime of all servers each day, and the sum of the downtime of all servers for each day for the last month using the graph method in RRDTools. I want to display this in the same graph. Using the build-in feature in Servers Alive (File->Setup->Logging->RRDTools->"Generate CREATE script"- button) I am able to alter the standard CREATE script to what I want. However I am not able to alter the GRAPH script. And my first question is: 1) Is it possible to alter both the graph and create script in Servers Alive, or to I have to build the graph script separately? By using the create script below a bat file that generates several rrd files (This script may have several flaws): rrdtool create Graph/filename --start now-30d --step 60 DS:stats_uptime:DERIVE:1000000:U:U DS:stats_downtime:DERIVE:1000000:U:U RRA:AVERAGE:0.5:60:744 My second, and most important question is then: 2) How do I summarize the downtime and uptime of servers, and display this in one graph? There are four statuses I eventually want to display : up, down, unavailable and maintenance I am able to display the header and vertical label that I want, but that's about it..
