%title\r\nSeverity: %severity\r\n{if %state == 0}Time elapsed: %elapsed\r\n{/if}Timestamp: %timestamp\r\nUnique-ID: %uid\r\nRule: {if %name}%name{else}%rule{/if}\r\n{if %faults}Faults:\r\n{foreach %faults} #%key: %value.string\r\n{/foreach}{/if}Alert sent to: {foreach %contacts}%value <%key> {/foreach}
