Change color on ping?

[steff1977]

Hey

I cant quite figure out if this is dureable in 0.9.

i want to have a node or link that changes color if the ping gets to high.

there is a lot of new parameters with TARGET is just can figure them out

can i make something like this

NODE testping
LABEL ping to server12
TARGET rrd:/var/www/html/rra/ping.rra
USESCALE ping

Best Regards Steff

NODE testping
LABEL ping to server12
TARGET rrd:/var/www/html/rra/ping.rra
USESCALE ping

As long as you define the new scale called 'ping', then yes, that's right

Code: Select all

SCALE ping  0 20   0 255 0
SCALE ping 20 100  255 0 0

One warning: even though it doesn't look like it, the SCALE lines are STILL PERCENTAGES. It just happens that for NODEs the default MAXVALUE is 100, so as long as your values are below 100, then everything works as expected.

If you have a global WAN, you might see ping times over 100ms even on idle links, so you will need to do a little math. I do this for our temperature map. The SCALE lines are set so that 50% is the perfect green, and MAXVALUE is set to twice the ideal value. Since the temperature will never actually double (unless the building is burning down), then we never go over 100%. If you set the scale and maxvalue right, then usually if it goes over 100%, it's probably a bad thing anyway, so 90-100 can be red, and if it clips to 100, then it's still OK being red. I hope that makes sense!

Ok it got something.

But it looks like it just returns 0? but the graph looks fine

Here is what i have done

SCALE ping 0 20 0 255 0
SCALE ping 20 100 255 0 0

NODE Ciklum
LABEL Ciklum
POSITION 586 540
TARGET rrd:/var/www/html/rra/ciklum_net_ping_292.rrd
USESCALE ping

LINK Ciklum-Ping
INFOURL /graph.php?rra_id=all&local_graph_id=282
OVERLIBGRAPH /graph_image.php?local_graph_id=282&rra_id=0&graph_nolegend=true&graph_height=100&graph_width=300
NODES Ciklum Ping
TARGET rrd:/var/www/html/rra/ciklum_net_ping_292.rrd
USESCALE ping

Any idea why it just returns 0

Oh. One other thing

In the TARGET lines, you will need to specify the RRD DS name, which probably isn't the default (traffic_in/traffic_out). You can see this by looking in Data Templates, at the Data Source Item name for this template. Once you know it, you add it to the TARGET line like this:

Code: Select all

TARGET yourrrdfile.rrd:dsname:-

(you don't need the 'out' value, so just let that be 0).

Thanks for the quick responce
but you lost me a bit there


TARGET yourrrdfile.rrd:dsname:-
?
Should i have 2 TARGET linies? or like this

NODE Ciklum
LABEL Ciklum
POSITION 586 540
TARGET /var/www/html/rra/ciklum_net_ping_292.rrd:ping:-
USESCALE ping

SCALE ping 0 20 0 255 0
SCALE ping 20 100 255 0 0

NODE Ciklum
LABEL Ciklum

TARGET rrd:/var/www/html/rra/ciklum_net_ping_292.rrd
USESCALE ping

LINK Ciklum-Ping

Like that. As long as 'ping' is what the DS is called in your rrd files. There should only be one TARGET line in any node or link.

almost there

i added a maxvalue of 500, what happens if it gets over 500? or timeout?

LINK Ciklum-Ping
MAXVALUE 500
INFOURL /graph.php?rra_id=all&local_graph_id=282
OVERLIBGRAPH /graph_image.php?local_graph_id=282&rra_id=0&graph_nolegend=true&graph_height=100&graph_width=300
NODES Ciklum Ping
TARGET /var/www/html/rra/ciklum_net_ping_292.rrd:ping:-
USESCALE ping

but the data i multiplied by 8. how do i change that.

and is there a way to only have a one way arrow, i can "hide" the number useing BWLABELPOS but can i have only one arrow?

It will clip the percentage to 100, and use whatever colour your have for that. I don't know about your network, but once it gets to 500 in mine, then it doesn't matter too much if you can see how much more than that it really is. It's a bad thing anyway.

but the data i multiplied by 8. how do i change that.

Ooops. TARGET gauge:/var/www/html/rra/ciklum_net_ping_292.rrd:ping:-

Gauge stops the *8 part.

and is there a way to only have a one way arrow, i can "hide" the number useing BWLABELPOS but can i have only one arrow?

No. That is something I want to add in a future version.

[steff1977]

that gauge did the trick.. but :|

the number is 75,2 and so is that graph, but it is still green?

SCALE ping 0 50 0 255 0
SCALE ping 50 150 240 240 0
SCALE ping 150 500 255 0 0

NODE Ciklum
LABEL Ciklum
POSITION 586 540
TARGET gauge:/var/www/html/rra/ciklum_net_ping_292.rrd:ping:-
MAXVALUE 500
USESCALE ping

Thanks for the great help so far.

SCALE ping 0 50 0 255 0
SCALE ping 50 150 240 240 0
SCALE ping 150 500 255 0 0

These are percentages. They should only ever go up to 100.

So if you have MAXVALUE 500, and the actual ping was 75 or so, then the percentage is (75/500) * 100 = 15%, which is in the first band of your scale.

This makes a lot more sense if you consider that it originally was meant for bandwidth on links sorry about that

My bad. it works

it is no problem thats it is in %, when you just understand it, all it take is a little math

If i want the input and output to be the same, so the line between the 2 nodes is the same color, if i look at the docs it should be like this right?

TARGET gauge:/var/www/html/rra/ciklum_net_ping_292.rrd:ping gauge:/var/www/html/rra/ciklum_net_ping_292.rrd:ping:-

Other that that, i just works like a charm, time to make a map

To do it so that both sides are the same colour:

TARGET gauge:/var/www/html/rra/ciklum_net_ping_292.rrd:ping:ping

should be enough. This makes both the values from the same DS.

We got there in the end
